Best to have both versions so you can decide for yourself, but in the case that you can not... V1 gets 15-20% better range and has a more predictable off road attitude. The plus rides all the same terrain as the v1 but does strange things on loose conditions, washboard bumps or small drops. If you are in a need for speed scenario get the plus. Get the v1 for trail riding and long range. For myself I commute to work on the plus and ride off road on my v1 after I get home in the evening... You will not regret having both.

RE: Firmware 4000 vs. 4001...any difference (and how to upgrade)?
My board is 4000 and a couple friends have 4001. They felt identical in almost every way. The one thing we all noticed was that all 3 pluses had a different balance angle. My 4000 was the middle angle and one 4001 was leaning forward, the other leaning back more. Wasn't totally conclusive that it was a firmware thing but maybe a gyro thing.
