Character specific gear is very valuable. When picking up character specific items, such as "Iron Man's Coil", it is described as doing +3 Damage and +3 Rocket Uppercut. This is not +3 to damage for the hit; it means that it adds three dots in the Powers area. With this single item you can go from 129 Damage to 289 Damage.

Hard-to-beat team
Okay, the way I have a very hard to beat team is:
First use the 'All Characters' cheat.Then pick Ghost Rider. Level up his Penant Stare, Flechette Chain, and Damnation as much as possible. Next, you pick Doctor Strange. Level Up whatever you want on him. Next is Silver Surfer. Make sure you level up his 'Molecular Mix-up' and basic energy beam. Lastly, pick Spider-Man. Level up any long-range attacks from him. Those are good. I beat the game seven times in one day with this team.
How to beat mandrin
When mandrin has gone up in is teleport pad and released the spder bombs get a flying character. Hover over the correct teleport pad. The spiders will go under you and teleport into the room and blow up the ultimos so you can go on the teleport pad and attack mandrin.
Infinite Experience
In Mephisto's Realm in the beginning area with the alter that reads, "Thy way shall be lit by the flames of impure souls." you can garner huge amounts of XP (infinite, if you wish) in a very short amount of time. Where the demons spawn, they will instantly respawn after every death. This is the fastest respawn rate that I've run across in the game (much faster than the Omega Base simulation missions' infinite spawn room or the Asgard simulation area). The demons respawn so quickly, that throwing attacks that return (Thor's hammer throw, DD's Extensive Strike for example) can actually kill one on the way out and one on the way back.
If your heroes are capable of quickly killing (one or two attacks) these low HP mobs , you will rapidly level all of your heroes or get costumes of heroes you don't already have. Thor's Mjolnir's Might or Dare Devil's ES seem perfect for this and only get better as you quickly level. Alternatively, you could throw the demons over the edge (*not* into the lava in the center, or the portal will open and the mission is over) but it isn't very quick. There is no need to worry about mana expensive, the blue orbs start popping so quickly that soon all of the orbs are just adding to the XP.
After a very short period of time, you will start seeing full-momentum orbs start to pop out too, which means that you can start using your Extreme attacks on a regular basis. Rising 16 levels in less than a 30 minutes is probably very doable.

Recommended team
Use the following trick to make a hard to kill team. Create a team consisting of Wolverine, Blade, Luke Cage, and Ghost Rider (Bad To The Bone team). The team bonus will be that 5% of all damage will be regained as health. Also, all these characters have a way to regenerate health. Equip the following outfits. For Wolverine, Astonishing, max out Health Regen and Defense. For Blade, Ultimate, max out Health Regen and Defense. For Luke Cage, New Avengers, max out Health Regen and Defense. For Ghost Rider, Original, max out Resurrect Ally and Defense. It is also recommended that Ghost Rider be equipped with The Heart Of Mephisto (10% of attack damage turned into health) or a similar item because he is the only character without a Health Regen. Equip other characters with gear that increases defense or dodging capabilities. Not only will your team be difficult to hurt, but they will be absorbing and regenerating most of the damage they take. If a teammate dies, Ghost Rider will have about a 50% chance of resurrecting them. Note: Ghost Rider is the weak character. He does not regenerate, and if he dies resurrection is lost. Also, Wolverine will regenerate the fastest because he has an inherit ability to regenerate in addition to the suit's bonus.
For easy health, experience, energy, money, and Extreme Momentum Orbs for leveling, create a team consisting of Luke Cage, Elektra, and Dr.Strange. When they each have a full Momentum bar, get a group of enemies around you. Then, use the power. Elektra will stun all enemies with her Curse of the Hand. Then, Dr. Strange will use his Mystic Maelstrom to kill all stunned enemies, causing them to drop Extreme Momentum Orbs for each enemy killed. Luke Cage will use his Sweet Christmas to kill any of the remaining enemies, giving you +472% more money for each enemy killed in the attack sequence. This trick is especially useful for leveling characters, unlocking costumes, and maxing out stats. The best place to do this is in the Shield training simulator on the Thunderball mission. Even if you run out of time you will still get the levels and money; do not worry about killing the Boss. Just get your momentum on Luke Cage, Dr. Strange, and Elektra.
