My last house and pool build was in Narcoossee, not far from you! We had all Jandy equipment, which was okay. I tend to appreciate the the Pentair filters and pumps a bit more. My biggest gripe was the filter. I had an 8700gal pool/spa and the Jandy 150 sq ft filter. I had to clean the filter every 3 months, and that was after procrastinating for a month every time. Really seemed to need it every two months, and that was with a screen enclosure. I wish I had a much much larger filter, like one of the Pentair Clean & Clear PLUS 320 models.
I suppose if it was no cost difference you might as well get the larger heater. I had the JXi 260k and it always heated the spa up to 102 in about 20-30 minutes. I didn't use it to heat the pool.
+1 for more lighting. I had one light in the pool and one light in the spa and it always looked weird because large parts of the pool were too dark.
If you aren't sold on "salt" yet you need to be! I maintained my pool in Narcoossee with bleach and liquid chlorine the old fashioned way for about two years before I got fed up with it and converted to salt. It is just much more stable chemistry. In FL with our sun and UV, a LOT of chlorine is used during the middle of the summer. If you get lazy, travel, or forget to add chlorine for a few days, you may go to swim and realize you have algae starting. Maybe its a couple days before a pool a party and now you have to shock the pool to get rid of the slimy feeling before the party and your levels will all be off and your pool will reek like chlorine for your party. Ask me how I know

Only had to have that happen twice before I converted to salt. Never again....
