I have both types of tanks and they both come with challenges specific to each.
I have found, depending on the species, macro tanks are a little more work than SPS for me. With SPS, I can throw in herbivores and a diverse clean up crew to eat nuisance algae. In a macro tank, I have to be very specific about what to use for nuisance algae.
For me though, SPS seems to do well with stability and upkeep of dosing amounts as things grow. With macro, there are a ton of variables to factor in besides the big 3. Macro going sexual , dosing way more things than I have to for SPS and then nuisance algae control.
Add in the above and I still have to dose for alk, calcium and mag. It gets a little tricky at times. While macro does not use a ton of that, some of the clacified macros do and then there is coralline algae lol. It loves that stuff.
End of day for me, both are pretty easy after all of the years of work put into them. I just keep up on dosing for whatever, trim macros as needed and enjoy my tanks. All with the added benefit of occasional GHA removes from the macro tanks lol.
