Help me understand Bitcoin Cash's role.

Hi,

First up, I own BTC, BCH, and BSV.

I genuinely want to know in a little more detail how BCH differentiates itself.

First, let me explain my understanding/perception of the role of BTC and BSV.

BTC - the role is clearly to be a store of value. This is why people are buying it. Sure, it doesn't adhere to the white paper, but the market does not care and they like the store of value idea and it's working (so far).

BSV - this is aimed to take Bitcoin back to satoshis original intent for the cryptocurrency - to be a scalable, peer to peer electronic cash system. I also understand the protocol is locked (or will be locked).

BCH - I kind of got lost with the fork with BSV. To me, It feels so similar to BSV but with the difference that BCH does not scale as greatly as BSV? And has higher fees? I could be wrong but this is my understanding.

So BTC is clearly differentiated, I get that.

But I don't quite understand why one would choose BCH over BSV? And please don't bring Craig Wright into any explanation.. I don't care for that. I just want to know, technically and practically, how is BCH different from BSV aside from having smaller block sizes (and why is that anyway?). I believe BCH has more merchants using it currently? But that's just a short term stat and no advantage long term.

So if BSV scales better and has lower fees, isn't that better as a currency? I feel like BCH is in this "middle" position somewhere, and I don't quite understand it.

Looking forward to learning.
