1) Like what you like. Don't let me or anyone else tell you what to like.
2) To answer your question, my experience what similar. I kept play 4 string basses and passing on the 5. For whatever reason I ordered a Carvin 6 string bass on a whim. I literally had to get my 4 string basses out of my house to FORCE myself to get used to it. After that, I did a ton of gigs with that bass. But it never felt like "home". But after I got used to the 6, and got a chance to play a 5 again, that's when I settles in on the 5. I play mainly 5 strings these days. But I own amd use several 4 strings when they work better for a given gig.
But that's all my experience. You walk/enjoy your own path.
No 5 string will feel "natural" from the first moment you hold it. If you set your mind to owning a 5, you'll need to pick one and stick with it for a while. Only then will you know if the 5 is for you.
Spot on advice!!!
And my journey from a 4-string to a 5-string was very similar to yours. I bought, -and later sold, three different 5-strings. Each was a spectacular failure on my part, and none of the basses were at fault. I just had a mental block in regards to the B-string. I just couldn't get accustomed to it.
A couple of years later, my wife saw me looking at a 6-string bass online and encouraged me to order one. When it came in, I figured I'd learn it at home, at my own pace.
But my band mates really liked it's sound, and they encouraged me to play it on our gigs.
I was playing wrong notes all over the place at first, but they kept encouraging me.
I quickly realized to play only my E,A,D, and G strings, and gradually start using my B and C strings. And I'd actually think of note names before I played them. I also work-shedded heavily at home, learning my fingerboard.
A couple of months later, I felt pretry comfortable playing my 6-string full time. Then, I bought a new 5-string, and it was finally quite easy for me to play.
It was quite a strange way of doing things, but I'm glad it worked. I enjoy 6-string the most, but now I can switch between any of my basses, and I feel pretty comfortable doing it.
