Infinitely easier in the UK: you don't need capital, the forms are simple, it costs virtually nothing and you'll be done in less than a day.

Now you can start a UG with a 1,- Euro investment (more like 500 Euro min because it still has to cover setup fees). Which I think has made the UK thing superfluous, just complicates things even more.
Note that a Limited doesn't free you from having to deal with the local authorities (Gewerbeamt in Germany, tax office, etc).
Probably after brexit this will be still a competitive advantage of the UK against other markets.
I advise against.
