Vario has negative points too:
Relatively small carrying capacity because of the internal expansion hardware
I'm sure... as all cases/parts have pros & cons. But I have had a good experience so far. I can fit my full face helmet when expanded and don't have to carry it around when I get to the office.
I'm sure there might be cheaper options out there. I never saw one I liked or that matched the bike. My take was after spending $24K on a bike I'd be OK with pitching an extra $1000 for Top Case (including carrier, backrest padding and lock set to match ignition key) and handguards.
