I've read a whole lot, 6 months of reading. So far I am still using carto
tank on ego batteries & even graduated to an ego twist. My 30/70 VG juices I bought are weak tasting. I still smoke my home rolled cigs cuz I have a problem with the ejuices. I going to try adding additives to my juices, then make my own. I haven't graduated from ego's cuz I am not sure what to graduate to.
The most common reason for finding vaping unsatisfying is that there is not enough nicotine in the juice. What are you currently vaping and how much nicotine is in it?
DIY is a steep learning curve but very rewarding since you can design the flavour how you want. Just be careful as the most common mistake is adding too much flavour.
Different people look for different things - some like a lot of flavour, some like a big throat hit, and others like big clouds of vapour. I like a good bit of all of the above, but I've had to tone the flavour down a bit since I got my sense of taste back.
I can actually recommend menthol as a good vape even if you never smoked it. It makes a good vape and is pretty hard to get wrong.
Be aware that a lot of juice vendors will let you get double flavour shots if you like strong flavours, but do try the normal flavour first before you decide. Nothing worse than a juice that is too strong as it tastes like an accident in a chemical factory.
A twist is fine for most things, but you might want to look at the Innokin MVP 2 as it's a very useful vv/vw device that is still very small and portable. The Innokin VV V3 also rates a mention as a small device with excellent features. If you want a more usual tube mode then the Vamo, SVD and Zmax are all worth looking at for various reasons however with these you will also need to buy batteries and a charger.
The current flavour of the month for clearomisers is the BCC devices like the Protank 2, mini Protank 2, the T3S, Evod, etc and quite a few copies/clones/similar devices.
