The answer in my mind is it is better.
Many, many years ago while I was a child growing up in the earlier part of 1970's my relatives had a big fish tank which inspired my family to get a fish tank, then 2.
We had underground filters and used the old fashioned method of fish keeping add a couple fish do a few water changes and then add a few more. Repeat.
Fast forward to many years and keeping mostly Bettas and commonly kept community fish to 2012 when I really was interested in learning more about keeping fish better due to a confounding Bacterial bloom. After a month of issues with pearly, milky white water I learned some things which were life changing for the positive.
There is a thing called beneficial bacteria.
Later learned the process name - this magical bacteria processes aquarium waste in a process called nitrification cycle. Cycling was part of keeping fish better.
A great resource, would be to read up here is one nice article about starting a fish tank, which you already seem to be good at.

You can check it out and think about how it might make your fish healthier and happier.
Think of why you keep them.
Most people here find them to be special creatures which are kept in ideal conditions to ensure their best life possible.
Fish store workers can be amazing but a huge number of them do not know what they are doing, lacking experience and training.
Reason you were sold tropical fish, preferring warmer water to go with your cold water fish (which I use the term "cool" water fish most often). And Angelfish to eat smaller fish.
Being that your tank seems to work is okay, but are you happy with okay or try using best practices to get a better experience for the fish.
Firstly, one of the MOST important things I learned was DO NOT throw away the filter pad (basically ever, till it is falling apart).
You will discover the BB (beneficial bacteria) grows there in the greatest amounts and processes the tank waste. Throwing it away removes the BB system in place to keep a smooth running tank biologically speaking.
It causes hardship and injury to fish internally if the tank doesn't have this system keeping their water conditions safe and out of the danger zones.
