Well, "easier to use" is relative term. People may *think* some product is easy to use, but in reality it's just a misinformation and they finish their product in a month (thinking it was quick and easy), when with other products they could do it in a week (they can't even imagine that).
Talking about PowerDraw - it is easy to use yet powerful; it might look similar to DelphiX in some way, but it's different in concept. PowerDraw alone can be used to make a complete game; for sound it's good to use either FMod, Bass or Housemarque (aka Midas). I'd also mention that I've been in contact with Jarrod Davis and would like to say that his graphics library, GameVision 2 would be a good alternative too. Actually, to be honest for just a little moment (don't think I'm promoting or something, it's just my opinion, as a programmer), I think now DelphiX is no match for PowerDraw, there's no such project that would be made better in DelphiX than in PowerDraw.
