Depends on soo much...but it's a bit of a toss up. Data
There are two big differences between Rogers and Bell with Blackberry: Data.
Rogers has a cap on their unlimited data: 25mb and Bell's is 100mb.
I use a chat client similar to Verichat, plus an RSS reader, recieve a ton of e-mail, and surf the internet frequently on the Blackberry. I use approximately 32mb/month.
So, I only pay $60 for the data (Bell Unlimited Plan)
The same usage on Rogers for the Data would be:
$60 for the Rogers Unlimited plan + ($7 x MB's over) = $109

Then there's the MDS/TCP issue.
To use a chat client, RSS Reader, or pretty much any cool 3rd Party Application that needs an http connection...for Yahoo, you'll need Verichat, I think.
on Rogers, you're good to go, on Bell, you need to be on a BES.
That's going to cost approximately:
$9.99mo USD + a one time RIM license fee of $39.99 USD through www.exchangemymail.com

which will also let you sync all of your PIM wirelessly (added bonus)

Then, there's the Hardware.
Rogers is the first Canadian Company with the 8700r complete with EDGE for faster bandwidth...coming soon
But Bell is coming out with a 7100 series that's supposed to have EV-DO, which will provide the fastest surfing broadband on the market...and should allow users to tether to laptops for surfing...coming soon.

And the other rumour is that there will be a handheld software upgrade to make all 7250's run on the 1X-EV-DO system.
More info: 8700 forum and rumour mill... Tethering
Currently, through directions posted in this forum, you can tether your Blackberry as a modem for a laptop with Rogers (most newer models), but not with Bell (yet...fingers crossed).

I think if you can wait for: EV-DO and Tethering, but you still want to get rocking with the hardware you suggested, Bell Mobility is the way to go.
Using my usage as an example, you would save approximately $35/month, and sync everything Wirelessly, though you would have a bill for Bell and a bill for ExchangeMyMail. A slightly more expensive option would be Bell's Hosted Mail Option, but that would then consolidate your charges onto one bill (it's $25/month for full service, though that's still a monthly savings of $10).

That doesn't even bring in the differences on the Voice Plans...
Hope that helps. Oh, and Go with Bell.
