I have been using a 6230 for some time now and I've been happy.

I've recently been given a used but perfectly functional 6230i and after
getting over the prettier screen and nicer camera relative to my 6230 I've
settled down into using it... except I find that using the same headset, the
voice quality is inferior to the 6230. This is a little disappointing!

Could this be down to inferior GSM reception or is it the Bluetooth
connectivity, or am I just unlucky with this handset?
