Most (not all) of the pump failures I have experienced seemed to be related to the controllers. So a pump without a controller such as yours, may last a long time. I just like the ability to adjust speeds.I use Sicce, I find them to be quiet, and reliable, and relatively inexpensive, some have 3 year warranties.
There are many flow rate sizes available.
I know some people like the variable speed pumps (more expensive), but I just use a PVC ball valve from the hardware store to control flow.
Much lesss expensive.

Since I keep riverine species, I require a strong flow (current)

The one above has been working on my 180 gal with 125 gal sump, 24/7 since 2020.
A feature I prefer that Sicce has are fittings that work with standard PVC from the hardware store
What kind of overflow and drain sizes are you running? How high is the water being returned and are you sble to turn pump down or is it running maxed outI just got one of these pumps and it is very nice. I got the most powerful one.
I like that it has an O ring seal on the outlet. Pump seems pretty quiet. I am starting to believe that paying more for a pump these days doesn't really mean quality.
I have been through too many expensive pumps. Some recommend Jaebo but let's face it. It's all made in China. Jaebo's didn't look any better than others.
This is the one I just set up today. Of course they are on sale - Black Friday.

cool great info thank you. I started building my 180 today. I’ll post some pictures tomorrow i forgot to get some today. I’m going to do dual 1.5” durso drains through the left side and I haven’t made up my mind if I want to run dual return pumps or just 1235 gal tank. 50 gal sump (~40 gal. during use) 1 1/2" overflow and 1 1/2" main drain. Gate valve on main drain to adjust flow and level in the return box.
2 return pumps with 3/4" OD tubing.
I have this pump turned down quite a bit. It's pretty powerful. Smallest barbed outlet on the pump is 3/4" so I had to heat up my tubing with a hair dryer to get it attached. It's pumping up almost 5 feet through about 5.5' of tubing.
Pump works great.
