Of course not everyone, but quite a lot of people go with Eheim Jaeger for glass or Finnex for titanium. Everyone is going to recommend a primary and secondary controller: Inkbird, Finnex, Ranco, controllers - RKE, Apex etc...
The Eheims have a controller built in as do some of the Finnexs.
It's also recommended to get two smaller heaters capable of heating your tank versus one large one.
The above recommendations are failsafes to avoid cooking or under heating your tank.
