My 2 favs up to this point are:
Voopoo Rune - Amazing flavor! Dripping on it is touchy since it's a bottom airflow similar to the kenedy. But it has a great top cap that comes off of the barrel easily. It really only shines when installed with coils that are pretty compact. The air holes are pretty narrow.
Vandyvape LIT - Good all around. Not the beast at anything but no matter your vape style it will handle it well (excluding mtl). HUGE juice capacity. Decent amount of room for larger builds. 2 airfow options, both of which are adjustable. Wide open is TONS of air and you can close it off to almost nothing. Dripping is easy. The clamp has a nice divot on either side to direct the juice towards the coils. And if you drip to hard on one side the squonk hole at the bottom feeds both sides so it will even out over time. Haven't tried to sqonk on it yet.
I have a 8 rda's. Well, 6 if you want to get technical about it. 1 is an rdta and one is an rta. 2 24mm Goons (original). 1 brass and 1 copper. 1 Vandy Vape Icon. 1 Armageddon Gen 2. 1 Digiflavor Drop. 1 Hellvape Dead Rabbit. 1 IJoy Combo rdta. And 1 Vaporized Nomads Pangaea rta.
Out of all of those I love my Goons but the Drop and the Dead Rabbit stand out. The Dead Rabbit having the edge in the end.
I have 9 mods so far. 6 mechs, 2 regulated and 1 pod but I'm thinking that would a bit off topic and I'm not trying to write a book.
Wire and builds however. Ni80 and SS316 without question. Mainly clapton and a little bit of round wire. I really like staged heating coils. Single tube dual coil builds @ .09-.12 ohms and series stacks @ .25-.3 ohms. Just my preference. I am by no means suggesting that anyone build that low.
Dead Rabbit for single tube dual coil build is great. Same for squonking. Over squonk a Dead Rabbit and something is bad wrong.
I use the Icon for series builds primarily.
