The machine runs cooler than the 3401.
When using proper technique heat isn't an issue with the pads. Especially pads with the hole in the center to dissipate heat more effectively.
You don't use the downward force with the long throws like you do the Flex.
I agree.
I think in my RUPES how-to book one of the things I share is to take everything you've learned and know about buffing with all other polishers, as far as technique and throw it out the window.

Correct, you don't have to push down on the machine like a Flex. Light pressure and let the machine, pad, and product do the work.
I may have misunderstood the question are you asking about those two machines vs a Rupes, or comparing the 15 to the 21.
When you say more powerful, do you mean more pad spinning torque?The 15 is easier to use on tighter areas,the 21 is considerably more powerful. Thats the most simple, direct, truthful answer from someone who owns both.

Makes sense. The momentum of the huge 21mm throw in itself helps with rotation.Yep, definitely more torque turning the pad and keeping rotation. You will find most rotation complaints on any brand long throw being on the 15. The 21 especially the MKII has the best rotarion and outright grunt. The 15 MKII will still be more power than any long throw on the market but not the 21 MKII.
Zubair, do you use a washer in any of your Rupes?
In your opinion, is there a NOTICEABLE power(pad rotation) difference between the MK1 15 and the MK II 15? I was unimpressed with the MK1 15 as far as pad rotation.Yes I do but no need with the Kamakazi's that are on there now. The MKII's seem to benefit more from being free than the MKI's. The 21 MKII is ridiculous in correction just like a rotary and should come with a warning, not because it will burn paint but because it removes paint unlike any dual action in existence.

Good stuff. Thank you.Yes there is but I am very critical so my noticeable and yours might be different as its very subjective. However....Don't get too caught up on rotation. The question you should be asking is there a noticeable difference in correction between the 15 MKI and MKII, then yes there is. What spoilt it for me was I didn't go from a 15ES to a 15 MKII, I went big one time and went 21 MKII. I then shortly bought a 15 MKII as they claimed it closes the power on the 21 through higher speeds. So I thought cool, insane cut plus versatility of a shorter throw. Turned out that wasn't exactly true, its more powerful than an ES but nothing like the 21 MKII in correction. 15 MKII is a very nice all rounder, smooth,powerful and useable. It will outcut all other DA's but having owned the 21 MKII just before it kinda spoilt it for me. If I didn't own the 21 I would be singing songs of the 15.
Precisely why I don't take opinions on this forum by people who don't own all as they only know what they own and rave about it without knowing theres better out there...much better...
Good stuff. Thank you.
MK II 21 with a 5" BP would seem to be a great. The 5" backing plate would make the 21mm throw a lot more versatile. I'm just guessing, tho...
