Krokus 66 SL vs Meopta Opemus 6

Hello :)

i would like to buy an enlarger for the 6x4.5 medium format but also for the 135 and I'm undecided between which one to get.

il krokus It appears to have a negative holder and allows you to adjust the mask as you like based on the negative you are using:

while Optemus 6 don't looks like it have that feature !

Can someone give me an opinion ?
