Still depends on what you're flying, try taking off in something with nearly 1000shp swinging over a 100 inch four bladed prop without some rudder trim, great leg workout
Or rolling down a dirt runway in a loaded 206 with 0 flaps...
I thought we are talking about a pre-landing checklist in a complex plane.
The somewhat humorous take on the 'GUMPS check' is simply to emphasize that the most important item in most light aircraft is the 'U' one.
Gas: I dont care about gas in the pre-landing checklist, should have switched to the fullest tank at top of descent, at pattern altitude is a bad time to switch to an empty tank or to put the fuel selector next to the detent. Putting the aux pump on should again not be something automated with mnemonic but a conscious decision, what is a valid checklist item in a Cherokee will leave you with great quietness in a 210. Yeah, its worthwhile to check that I am on the tank I wanted to be (usually a main, not a tip).
Undercarriage: Care very much about that one, over and over. But rather than making it a cursory point in a checklist, it should be 'gear, hand on he lever until 3 green and three in the mirror'
Mixture: Not really an issue, I have already enriched while descending, shoving the mixture forward mindlessly during a checklist may leave you with quietness if for some reason you ended up with a rich mixture to start.
Prop: Again, I have either gone to high rpm during the descent or I'll leave it at 2400 or so, the plane will fly an approach at lower rpm just fine, no need to wake up the airport neighbors with that 'waaaioouu' sound that you create on the outside by shoving the prop forward mindlessly at pattern altitude. If I need rpm for a go-around, the lever is right next to the throttle, I can grab both at the same time with my big paddle hands.
So rather than mindlessly going 'GUMPS, GUMPS, GUMPS' and still landing gear up, I try to focus on one, making the gear extension a conscious act and the checks during the approach to focus on the effect (seing the gear in the mirror, having the 3 lights) than any kind of mnemonic.
