I've always just went GH products because they have the little cool test kit and availability/popular. However I was thinking about running something different. What PH UP/DOWN solution are you using and why? Thanks.

Bloom City for me, no one does a really good organic one. I used Bloom City PH down mainly. My tap is 8 out of the faucet, so it takes just a couple drops. A bottle lasts me for at least 4 to 5 grows (2 to 3 plants a grow, twice yearly).

I use powdered citric acid for ph down.About 1/16 tsp per gallon puts me at 6.0 I've never had an occasion to raise the pH.

I use silica to raise pH. Obviously gives silica as well as a little K.

My feed is acidic so no need for pH down

I have seen PH- products marketed for bloom since they are phosphoric acid but the small amount you should need won't make a difference.
I don't need any PH adjustment in general but when I need, citric acid for PH- and bicarbonate soda for PH+. All in powder so it's easy to get a consistent amount all the time.

With rain water, I'm in the same boat as @Nutty sKunK , my solutions are always acidic. I make stock solutions with Agsil16.

I still have a gallon bottle of phosphoric acid around somewhere, it's lasted my around 10 years.

I use GH Up but I switched to pH Down from ChemBoys instead of the GH version. It's about the same price, IIRC, but more concentrated.

Get a small jug of sulfuric from car parts store and some distilled water. And/ or some Citric powder from the grocery store. I treat well water with a little sulfuric then mix nutrients and use the citric to fine tune. There is no need to buy it from GH or anyone else.
