I moved into a house back in 2002 with a pool already in place, it has a DE filter/Chlorine and deep end with a diving board. Personally, I loved having a deep end, I guess it's a matter of preference, although in Texas, you won't find many pools with a deep end. The pool we have now is shallow, there are plus and minuses to both. We moved to a new house, but I still have the old one as a rental.
When we moved to the new house, I had a pool put in. This one is salt water with a cartridge filter, which I like way more than a DE filter and chlorine pool. The maintenance is alot less, but it did take some time to figure out some things. Cartridge filters are easier to maintain and clean than the DE and you don't have to use DE. Also, if you have to re-order the filters, it's alot cheaper to do it online and have them shipped then to buy from a local pool supply store. Generally, the pool company I used, I wasn't real pleased with. They always seemed to rush me with decisions and didn't give much guidance. Plus, they screwed up the initial order where they installed a chlorine system, not salt, so I had to battle with them on that. Also, my system works off an app, so if I want to turn on the hot tub, lights, set temps, etc., I can do it through an iaqualink app or online via web browser. I love it, because we can be out having dinner, etc. and I can start the hot tub. In the winter, the hot tub can take a while to heat up. Keep in mind though, it will connect through your home wifi, so you'll need a good speed, or it will drop and kinda a pain in the *** when it does. Ours also has a connector hose going from the outdoor spigot, under the decking, into the skimmer. This is nice, because if you need to add water, you can just turn it there, without having to run a hose directly in the pool. It may not be as much of an issue in upstate, but in Texas, we have alot of evaporation in the summer, so I have to add quite a bit weekly in the hot months. Also, the pipes feeding water to and from the pool filter, are side by side, not stacked, so if there is some issue with one of the pipes underneath, it's an easier find and fix. The company should explain that as well when they show the design. That's about all I can think of right now, I'll add to it if I think of anything else.
