The First class on UA to FRA is on B747 or B777. It is the so called First Suite. This is the best in the industry. On F you also get the F international lounge + other amenities (Arrivals by United). The concierge service is high class.
I didn't go on LH metal to FRA because I am a dedicated UA customer and want to accrue bonus miles on MP and use my SWUs. However I have seen the F cabin on A340. It doesn't match the UA First Suite.
Last, the UA F/As on F are high class folks. One has to meet them to understand.
