Welcome and if you find the best liquid, please let me know, lol. I've vaped for a long time and still haven't found the best. I haven't even found a best brand, I buy from multiple places and such. Taste is too subjective and even then tastes change, you may love cherry soda but imagine drinking it all day everyday plus vaping a cherry soda liquid. Most (including me) would burn out of anything flavored cherry really quick.
Many have or look for an all day vape, I don't. I look for what I like and could stand if it's all I had left, until I could buy more or more comes in the mail. Try out as much as you can locally, order from places that offer sample sizes at a fair price, say $1 to $3 for 5mL. Just don't blow you budget on a big bottle of something, just because it's cheap. Seen many blow their budget because they gambled and hated the stuff.
Just remember buying sample sizes will cost more because you're paying for that little bottle but it is the cheapest option (other than local) to try new stuff. It can also lead you to try flavors you might never would, has me and I've found many things I would never have spent big money on, just to try it.
