Pilates (from what I know about it) will help with core strength, and with flexibility. Weight training will help you keep muscle you likely already have as you lose weight. I'd suggest try both and then see which you enjoy the most. I'm a little biased towards weight training as I enjoy it. However, in the end, the best exercise is one you enjoy - as it means that you're more likely to keep it up. Oh, and depending on your current level of fitness, 6 days a week might be pretty hard to keep up. I've done as much as 7 days a week but in the end find that 5 days a week is perfectly fine (preferably 3 days on, 1 day off, 2 days on, 1 day off). So I do 3 days weight training and 2 days fairly light cardio.
