If you do get 1.6, make sure you set these launch options:
-noforcemaccel -noforcemparms -noforcemspd
Also, you'll need to disable vsync through your graphics control panel to get rid of input lag.
If this all sounds too hardcore for you, steer cleer.

No one gets stomped in 1.6 because everyone who still plays it is terrible at the game.
Like anything in CS, it really depends on the server that you play. The best players don't usually pub, but you'll find some pretty ridiculous players out there anyways.
CS 1.6 has a lot more vanilla servers and long term players. Source actually has few vanilla servers, with a lot of them being the more 'fun' servers like gun game and the like.
Still, the engine is definitely less forgiving. The hitboxes are much tighter, and bullet control is much more important. Personally, I think the engine and netcode is a good deal better than Source. To the uninitiated though, they'll probably seem almost identical.
