Hi Norman,
This is a topic that surfaces every so often and is not an easy one to answer.
So my two penneth worth is this!
If you are only interested in VHF and above, Satellites and terrestrial work - the 910 every time.
If you want a shack in a box that can do (primarily) HF, then the TS wins the day!
The reason I say "primarily" is that the TS exhibits a "birdie" right in the downlink frequency for SO-50 which renders use of that bird more or less impossible on that radio.
Its like trying to compare apples with oranges.
For sat work (for me) the 910.
For HF work, the Icom 756 Pro series. :-D
Others will give you different answers of course but the main factor for me if I was buying a radio now would be the SO-50 "birdie" issue. It may only affect one bird but there are not that many left up there and no plans to get any more up!
