When the 195 was the biggest unit you could buy I was given it for my birthday and I enjoyed using it.
However since I flew with a III some time ago I think I would have been happy with that as I really only need a GPS for backup for bimbling (the aircraft I use for going places have panel mounted GPSs)
The main drawback of the 195/295/296 is the size of the thing and the associated need for lotsa batteries/powerleads etc.
But ultimately it is a balance only you can strike!
Have fun
