Ask yourself one question: If that Squier you bought had one string less, would you play it more?
What this gentleman said.
When the answer is along the lines of "No, that's an entry level instrument and I much prefer to play my very expensive pro level basses because the necks are smoother, the sound is fuller and the action is lower"
Then the answer to your question is "I don't know if you're limited to 5 strings, but I can tell you that you don't like playing cheap entry level basses while top notch models are sitting close by".
When the answer is more towards "of course I would, I really like the neck and the feel of it, it's just that I keep getting confused with the B string"
Then the Answer is:
You have not tried hard enough to get to a conclusion. Take all your four bangers and lock them up. Should you manage to practice daily, about seven to ten weeks will suffice. Play nothing but the 5 String tuned BEADG.
Nothing, not even for a few minutes. When you've brainwashed yourself enough so that the 5 String Platform feels like home (learn a few new songs and incorporate the B string), you can lift the lockup for your four string basses and see whether it feels like coming home after a long trip or if it's just a different bass with a different number of strings.
For some, it'll be like "meh, I can do either now"
For others it's "finally the right amount of strings again"
and then there are those that are "huh! this bass is missing a string. How am I supposed to enjoy myself on it?".
