How fiddly do you like your vaping?
If you want the best possible flavour and don't mind wrapping coils I'd get an IGO or an Octopus dripping atomiser, and I'd wrap 'micro coils' in it for maximum flavour.
I'd sit that on top of a ZMax. The V3 is the current model and you can get 2 different looks, a flat top or a slanted top. If you aren't too bothered about telescoping and using different sized batteries in it and are planning on using it in 18650 length anyway then you can probably find a v2 ZMax for less than the v3, electronically they are identical, only the styling and the telescoping parts are different.
Vamos are cheaper but they will wear out sooner, particularly the top connection threads are more likely to break. A Zmax is not without faults either. Inside the Zmax the electronics are glued in. On some units this can come loose causing the button to move off centre, which can give you occasional misfires. Of the two though the Sigelei ZMaxes are better build quality.
If you have budget to spend and want the best quality then a Provari is about the best VV thing you can buy - though it's 3 times the cost of a Zmax.
If you really like to gets your hands dirty and tinker then the best flavour is to be found on a Genesis atomiser, the easiest tank to learn to setup is an RSST, they're also relatively cheap though if you want to get the best out of Genesis then you'll end up with a mech mod as you need a lower resistance coil on a Genesis which doesn't work too well with a VV/VW setup. Cheap mechs are £40 (really cheap ones aren't worth the savings) but this is offset by the fact that you'll want to use high calibre batteries in them. You can use cheaper batteries in a regulated mod like a vamo or a ZMax as they have protections built in to them. Mechs don't so it's highly recommended to get high capacity IMR batteries for mech mods which bumps the overall cost up.
If you don't want a fiddle at all then I'd go with a Taifun or a Spheroid atomiser right now. Easy to use and setup but you're looking at about £100 for one. I'd rather spend money on a quality atomiser and an average battery than an average atomiser and a quality battery if I had to choose.
Atomisers like vivi novas or protanks are OK, but the flavour you get from those is no comparison to a dripping atomiser, so if you're after a sit at home in an easy chair kind of vape and don't mind dripping into it every so often that's what I'd go for.
An IGO L is about £12 an octopus is about the same price, enough wick and wire for a good while will cost you about £10 a v2 ZMax kit is around £65 a v3 Zmax kit is going to be about £80+ an SVD (similar to a ZMax v3 different looks) is about the same price as a v3 ZMax a Vamo kit is about £60 I'd probably get a ProTank as well £15ish for the times I didn't want to drip they're probably the best and most robust lower end tanks on the market atm. I'd stay away from Polycarbonate plastic tanked anything, a carto tank is a reasonable faff free vape as an alternative to a protank.
(all UK vendor prices) you can get lots of this stuff 'direct from China' but you have to wait 2-3 weeks+ for delivery and warranty/customer service can be patchy.
