Well simply and precisely, how you praised BCH I know it has these qualities of huge block size and blah blah blah but here we come to a genuine issue which is BCH is not distinctive. We have more than around 1300 alts look into them you will find even better options than BCH and then shift your funds as well, all the dump heads are doing it. 
I won't say BTC don't have issues yes it has that need to be fixed. Personally I have no issues with transaction confirmation but for me fee is a big issue. Transactions are delayed because people don't pay the proper fee to be on a priority base and that's it. I trade on binance, bittrex, local bitcoin exchanges my transaction never stucked.
Now the one and only reason why I like bitcoin? Because it's the pioneer and it's not been imposed on anyone to like it. People love it because it has proved itself on every forum anytime everywhere.

I know that there are perhaps more valiable options to invest in than BCH, hell even BTC, but im not trying to point that out here. BTC is pioneer, I agree, there is a reason why everything besides him is called altcoin. BCH is not the first and only coin forked out of BTC, I get that also, but as I said before, facts tell me BCH is more truer to original Satoshi vision than BTC is right now-BCH developed because of that in the first place, and facts support that. Thats the reason why imo its pointless to look at BCH as some shitcoin trying to take BTCs place.
The point is, both have their problems, but rn BTC is banged up and in really bad shape, and BCH is holding much better, price aside, look at the foundations what bitcoin is and what it can be. Satoshi wanted bigger block sizes, BCH wanted it, and it has it, BTC think differently, obviously. There is actually some sense when its said that "Bitcoin Cash is the real Bitcoin", taking these facts above.... In other words, they are "fighting" to be true leader what bitcoin is in the first place.
As you said, the one and only reason why you love BTC so much is because its pioneer and its proven etc. But if you know BTC has its serious problems and agree that BCH is maybe technically better solved to deal with these problems and its truer to "real Bitcoin", why still stick so firmly to it? Is it good enough to be pioneer and not being imposed on anyone to like it enough when the problems are much more serious and seems like its more or less stay that way?
Again, im not pro any of these, I would like to invest in both, just I want to clear some question marks I have behind understanding logic people like any/both of them so much, and why....
