I've had both types, play woods and scenario games.
I ended up with a 3.5, because i like the feel,smoothness,sound and general ease of maintenance .
(Not that an Lv1 is hard to maintain.)
Also the sandstorm colour was only available in 3.5.
I had about 4 LV1's in various colours, also had GEO,3,3.1 and a couple of GSL's.
Out of all of them i like my current 3.5 the best.
