The regular strength flavors are fine, particularly for someone who is just venturing out into vapeland. I would suggest you take advantage of sale to order a bunch of 5 and 10 ml bottles so you can get an idea of where your taste buds are leading.
You should also be made aware that most of us found that we didn't like tobacco juices that much when we first started vaping. I would get a good variety like sweets, fruits, a couple of the specialties. I don't know what or how much you smoked, but going with 18 mg of nicotine should be a safe bet. You can always order higher or lower mgs of the same juices and mix them together if you find that either too low or high an amount of nicotine.
Some of the most popular addictive juices include, Hypnotic Mist, PureCig, Wyatt Earp Blend, RY5(those three are tobaccos), Hopscotch, Orange Creamsicle, too many to think of right now.
The best thing working for you is, you can order as many different juices as you want in 5 ml sizes for practically nothing. It's enough to get a good feel for what they taste like straight out the mailbox and after steeping for awhile.
