I think in dslr canon is great you should go for eos 550d

The Sony NEX-5 is not a dSLR, you should be comparing the Sony A55 or A580 to the Canon 500D/550D. The Nikon D5000 should also be included as the D3100 is an entry level Nikon.
You are not comparing equivalent models.

Personally I prefer the EOS 550D but the E620 is very good value for what you get and the NEX5 is amazingly compact.
It's down to you really to work out your needs and make a preference. No one can tell you what camera is best for you.

I think you should go with Canon EOS canon eos 500d Digital SLR Camera
