Both are fun to play and have their advantages/weaknesses. I very much prefer my scout, however for me, it's a question of playstyle, the map I'm on, the game mode and the team. Scout is like Reaper/SS in the sense that you don't really need more than one on a team, and it can be detrimental in TDM particularly to have more than one Scout on a team, unless they're both Incredible pilots.
The Scout is the hardest mech to pilot in Hawken (in my opinion), though it can be the most rewarding. Scout is best for open maps with cover (bazzar, outside of facility), and functions much more as a support mech; somewhere here in the threads, someone mentioned that the Scout "ought to be circling around your team like an angry dog" I couldn't agree more. It's ideal for drawing fire, and attention, away from your teammates. It's great for flanking in TDM and other players battling in DM- sneak around and pulverize any/every c-class you can and get outta there before they turn around to greet you.
The hardest part about piloting the Scout is timing the use of your reserve tank ability and getting in close enough to do damage w/o getting pulverized.
The Infiltrator works out better for me in enclosed spaces (wreckage, the inside of facility). It's also great for sneaking up behind enemies while they're distracted, as well as inserting yourself in the line of fire for savior kills when your teammates are getting pummelled, providing them with a chance to escape.
Internals make a big difference in the A Class; a Scout or Beserker without an air compressor is an easy target when airborn. I also highly recommend a basic repair kit and learning how to duck behind cover, use it and pop back out.
I prefer Scout, though you'll have to figure out how and what role you'd like to play. After you've played the game long enough, you'll have every mech ranked up, anyway. Cheers.
