Commenting from Germany: the amount of Festool I have seen on jobsites is really quite high. Especially due to their good dust collection.

I get if people buy their tracksaw or similar but their drills do look like toys. On the other hand if you're already invested into their batteries and you then also need a drill maybe it makes sense to go with the same brand.

Most contractors I know use Hiltis and that's a lot more expensive than Festool. But there's a sayinh that I heard once: Buy contractor grade tools, never buy contractor grade consumables

If a battery powered tool don't belong on a job site then it don't belong in a workshop
