I think the clouper might be catering to me

I'm new to this, so could easily be thinking wrong. If so feel free to correct me
I currently build everything around 1 ohm. And vape my rbas at 30 watts on hana clone. I know I want more power, but I'm unclear where my eventual sweetspot will be.
The ipv3 at 1 ohm. would be able to give me up to 49 watts.
The clouper would give me from 31 watts to 150 watts. So without having to change my build, I could definitely get the wattage I want. The only downside I see is I couldn't use protanks or nautilus on it.
The Ipv3, If I decide I want hotter vape, I would have to build much lower. While that is doable, I would always have a MUCH lower range of possibilities with it.
The clouper v6 is also on my radar. As possibly the best of both. Its voltage is 3.6 to 9.8. So on 1 ohm coil it would be 13 watts to 100 watts. I could vape anything I own on it.
But really I like them all

Which I purchase will probably be because of how the reviews on each are. And probably even more on which comes in stock for a decent price first. I tend to not have much will power, So will probably buy it.
