Owned and played both systems....
PSPIt was the coolest gadget to come out at the time, and rightfully so. I was wowed by its sleek design, pretty screen and multimedia features. But after the novelty wore off, you just realise that it's a great system with poor selection of games. There weren't really any memorable games on the system, the ones I remember playing the most were Lumines, Hot Shots Golf and Darkstalkers. Add to that, a 3-4 hour battery life meant that my gaming experience was seriously hampered, having to recharge so often. My PSP was promptly sold off.
NDSLAfter the PSP came the NDSL. By the time I sold my PSP, the NDSL had a stellar selection of games. It had Castlevania, Advance Wars, Mario, and many other great games that I wanted to play. So I took the plunge and got the NDSL, and it has been a blast since. Great battery life, nice screens, and most importantly, THE GAMES!!!
NDSL has a good variety of games. For the old school gamer, we have the classic series like Castlevania and Mario to satisfy, whilst games like EBA, Ouendan all provided new, innovative games. In the end it's a win-win situation as NDSL caters for both hardcore and casual gamers.
What can I say, I can't imagine life without my NDSL now. Even if it doesn't play music or videos, it's an excellent gaming machine
