Former frog owner here, emphasis on the former. I'm just going to run down the list of reasons I don't like it and let you make your own decision.
1. Mineral pac costs $100 a season
2. Mineral pac adds copper to your pool, potentially causing staining and green hair
3. Bac pac costs $20 for about $7 worth of trichlor tabs
4. Bac pac adds CYA to water potentially causing overstabilization
5. BAM algaecide adds additional copper because apparently the hundred dollar mineral pac isn't enough?
In contrast, since removing the frog and switching to the TFPC method I pay about a dollar a day for chlorine and $40 every 2-3 years on my TF-100 refills. A few dollars a month for muriatic acid to lower pH, but I always needed that. My water looks and feels incredible despite containing 10 times the FC recommended by the frog. No smell, no cloudiness, virtually no problems.
But that is just my experience.
