BB Storm2 9550/9520 :: Storm 9550 Vs Bold

I have a bold 9700 right now and my dad is looking for a phone and he wants a bold 9700. before i get him one im wondering if i should get a different phone and give him my bold. I love the bold but the couple things that have been really bothering me are the dropped calls and over crappy service.

Hows the 9550 on telus? and would u guys suggest switching to one? Hows the keyboard for someone thats used to a physical keyboard? the only two phones i have had are the tour and bold 9700 and i really like the keyboard, but im willing to get something thats not as good for a bigger screen. I just dont want anything thats glitchy. Im pretty picky about my electronics and especially for my phone i just want it to work.

So basically my real question is is it worth it to switch to the storm? and are there any issues with the phone that someone thats a bit finicky would be pissed off at? (im not obsessed about little issues but keyboard is a huge deal to me)


Edit* and is the storm 9520 out? and does it run on hspa bands?
id like to stick to gsm and not switch back to cdma :/. and any other suggestions for phones if you dont think the s2 fits?

Edit 2* and whats all this about a 9550 gsm? is the 9550 a "world" phone? and if its gsm im assuming its the international gsm bands and i cant get gsm on telus?
