Should I buy Samsung i600 or HTC S620

[Trig8]

I am looking for a used (cheap) and light WM smartphone to comfortably fit in a suit jacket pocket for those occations, and with qwerty keyboard.
I am using a TYTN II now, which I will keep, but it is heavy and bulky.
Having my eyes on either the i600 or the s620, are there good reasons I should be aware of choosing one instead of the other? I can have both at the same price.
Right now the i600 looks most right due to being a bit smaller and lighter than the s620.
Anyone that have used one or both that can give some hands-on experience and suggestion?

I would suggest Samsung i600. I'm using this phone several years, used many other devices, but always get back to my old I600. And now more then ever I like my I600, thanks to Nokser, that gave second life to my Samsung with his WM 6.1.

Heh no this no suggest, but maybe ....:p

The I600 was sold before I got to it, so a S620 it is.
Maybe I'll add a I600 later to see which I like the most.
