Which is the best, AMD or Celeron procesor???

i prefer AMD since i am using one.I use AMD because --comparatively cheap --high performance --high stabilty --greater support for gaming i recommned AMD FX 64 bit computing.It has many advantage over intel pentium 4 processors.but i heard that intel pentium duo core2 is much better than other precedures and a like performance with AMD 64.so i f you are going to buy a new computer either you go for AMD FX 64 or Pentium 4 Duo core 2. thank you!
