I only have experience with TFA strawberry ripe, and FA strawberry red touch. IMO FA's is a strong, vibrant strawberry. TFA's has a sweeter taste, but not as bold. TFA's has EM in it as well to help carry sweetness. Me personally, I like to control the sweetness of my juices and tend to lean towards "cleaner" flavors.
That being said, I would tinker with FA strawberry and try and hone in on its characteristics, check out some reviews on other brands. I hear a lot of good things about Capellas sweet strawberry. FLV and INW are great companies as well. Good luck, hope this helps.
