It's all personal choice really, both have their positives and negatives so you need to pop to the shops and have a good look at a few sets. If you want value for money, you won't beat this offer from Richer Sounds at the moment, I just picked myself a set up today, only quickly plugged it in before going back to work but really pleased so far, specs are:

47" LCD
1080p 100hz
80,000:1 contrast
Freesat HD (and freeview) built in
24p mode for blue rays
3 HDMIs and all the other ports you need

and the price... £599 !!!

Although you might be lucky to get one, I was on the waiting list at my local shop and they have had hundred of calls about it.
