[warning... this is long... it is after all the story of what I have gone through]
I know that finding a good liquid flavor is largely a personal taste issue, but I was lucky... my brother in law started vapping a few months before me. It's funny, I made fun of everything he'd try when he first did it because it seemed so strange, but man am I lucky that he stuck with it (because in the end, I followed suit on most of his successes, and have been analog free [give or take 4-5 along the way] for almost 3 months).
I started with a Blu pack because they look like analogs and have the cool PCC. But when the carts would run out fairly quickly, I tried liquid that he had. At first, I thought I'd like tobacco (cause I smoked for nearly 15 years), but it didn't take long to realize that I don't actually like the flavor of cigarettes... I like nicotine.

So I tried several flavors (the Blu pack comes with 5, so I already was open to flavors like Menthol that I didn't use to smoke). In the end, I have settled on NHaler's Juicy Pear (can't say enough about how much I love it), and Totally Wicked's Menthol (for times when I want more throat hit).
I also eventually gave up on wanting automatic batteries exclusively, because I started dripping directly on my attys, and with automatics, that can really clog up when dripping. I tried manual batteries that fit my Blue attys (Joye 510 white batts) initially, but they require a different charger... so then I went to a Joye 510 pass-through with the Blu atty and cart (even though I strictly drip). Most recently, I wanted a way to vape longer than either a 510 or Blu (or Volcano, I tried those too) battery lasts... luckily, my brother in law had just gotten a Janty eGo kit, and I tried it. Wow! 6-8 hours of steady vapping without requiring recharging (and it's not the size of a hand cannon)... I rock this thing around the house all day now... no need to be tethered to the pass-through any more.
So the setup I have finally settled into is a Totally Wicked Tornado using Blu attys and an emptied Blu cart, that I drip with at home, and Blu's that I refill (using a modal mod in the carts) for when I go out to a club. It's been a long journey (and it's not over), but I am happy to say that after 15 years of smoking nearly a pack a day of analogs, I now have upgraded the habit, and am exclusively vapping instead!
Good luck with your own journey. Finding a liquid flavor that you like is step #1 in my opinion. Be open minded... there are a lot of great flavors out there... with a little testing (I suggest buying sampler sizes when you can) you will find at least one that works for you soon enough.
HV!
