To simply answer your question of what do I personally think is the best candidate from your list, it’s the FunOSR2 Twist with H200-1 + VESA - ~382USD.
However do I recommend you go for it? Hell no.
Why?
My reason for this is because of two factors, first is that you only just found out about this stuff 3-ish days ago so your still riding the Hype train of Discovery where everything seems PERFECT.
The second factor which is also more serious is that your going straight into the deep end of these toys by going for multi-axis and so high cost. You haven’t even tried an single axis stroker to see if just the basic slap together thing does work/appeal to you and your body. As there’s been many people whom have gone and gotten an multi-axis device like OSR2 or SR6 even and resold it on this forum, some of them even used an single axis stroker and went straight back to it.
My Recomendation
As a result my recommendation is instead something different, go basic setup get an second hand Handy ($145-ish Handy being sold on this site) and ask a friend or family member if you can borrow any sort of Stanley Multi Angle Hobby Vice and try that for an week or two. (It’s the easiest hands free setup in my opinion) Then from there mimic the multi-axis and twist feelings by using your hand to move the sleeve in that fashion since you’ll have had the Handy to show and give you the feeling of what you’ll be adding on to. After that you should have at least an vague idea as to how multi-axis, fast speed and of course hands free experience might be to then know better of what you want. (This is roughly how I progressed to an SR6 that I have now)
Because the king of multi-axis is SR6 hands down, you can upgrade to that from an OSR2 as you just need 3 more servos and some replacement 3D parts and case. (It’s also why I didn’t say T-Valve OSR2 since you can add that later and scripts for T-Valve are legendary-rarity) SSR1 is the fastest Single Axis stroker around however is not an finished product design wise (Tempest Max the maker of it and OSR2/SR6 has just recently release the Beta version of it to their Patreons) so it will have problems you will have to deal with. (more than the OSR2/SR6)
Also I recommend that if you do get an OSR2 get some spare 3D parts of the arms and the Twist clip gear spares made as I’ve had arms come broken and the clip of the gear break. Best if the gear is made of PETG instead of PLA material too since the latter makes the clip stiff and inflexible. Oh and while your at it, best to get some 3D printed adapters since the fleshlight is much bigger than onaholes but even some onaholes are differently sized…Handy sleeves meanwhile squish flat. M0SAIC’s Store website has most OSR2/SR6 stuff on it except servos. (Spare servos are best brought in batches rather than one at a time in my view)
Anyway I hope what I’ve said helps and also explains well why I’ve said what I’ve said. If you have any questions go ahead and ask and I’ll answer the best I can. (you can also search on this site for my other posts where I’ve talked about OSR2/SR6 stuff as I’ve probably left details out by accident)
