The 'better' depends on how you define it. If you mean cheaper,
yes GIMP if better because it is free.
But if you mean feature by feature comparison and/or easier to use,
Photoshop is better. If you find some reviewers who say GIMP is better,
that because they are OSS supporters, casual users, novice graphics
editors, non-profesional graphics designers.
Also MsPaint and LazPaint are better than GIMP if you just need it to do
some simple image resizing, cropping and text adding. It's just discussed
here:
http://forum.lazarus.freepascal.org/index.php/topic,37670.0.html I used Photoshop from 2004 - 2009, started to use GIMP from 2008 -
now. You can be a professional Photoshop user just in less than a year
of serious learning, you can be similar skill level in GIMP only after years
of intensive using/learning it. Not because GIMP has more features but
because working in Photoshop is more intuitive than in GIMP.
All the things you can do in Photoshop can also be done in GIMP. But
if you are a master in Photoshop you can do it lots faster in Photoshop.
I can show you a long list of features that Photoshop has but GIMP don't.
But I think no one here will be interested to know. So I stop here.
