They're both terrific choices.
If you like the frequency display, then the only Vector that would appeal to you is the V995 (which I believe retails for $269.00) while the Whistler XTR-695 retails for $189.00.
If you feel laser detection is a priority (you didn't mention it) then I'd give some consideration to the V995.
If you are looking for terrific Ka performance and a frequency display, then the Whistler would be a natural choice.
Again we're talking degrees of excellence, here.
You really can't go wrong with either of them.
