Happy to discuss any of these bad boys! All but the VaporGenie see regular use. I also got an old MFLB stashed aways somewhere that I bring out maybe once a year or so for a sesh but I forgot to include it in the pic and can't be arsed to take another one rn.
Definitely!
V3 wins for on the go use. Its form factor is close enough to an e-cig that nobody gives me a second look and I've even used it in very crowded places without issue. It extracts a bit faster, has a replaceable battery, is relatively easy to clean and has a sturdy, high class feel to it that you wouldn't expect from a budget device.
That said, the solo 2 easily blows it out of the water in terms of flavour and smoothness of the vapor. It also extracts a bit more thoroughly. I wouldn't pick up the V3 over it at home on the couch. A bowl takes a bit more time (with my use about 5 min for the V3 vs 10 minutes for the solo 2). It's even easier to clean and the battery capacity is massive. I've used mine almost daily for about 4 years, only since I got the BAK it's getting a bit less use and a charge still lasts for 10+ bowls.
Ultimately it's a question of your use case, if you wanna bring it with you and use it out and about a lot, go V3, otherwise solo 2.
