TimeMe Tile is so much cluttered and doesn't offer any other tile formats. Live Tile Clock 8.1 is "the" best app for the clock tile.
I agree that TimeMe Tile app is a bit messy compared to Live Tile Clock 8.1.
However, for my needs, it simply works: Got the time, the date, it updates fine, I can adjust the font, background colour/image, text colour to my liking to match my background. I can even add weather and battery status to the tile if I want to get crazy. As far as I remember, Live Tile Clock 8.1 didn't allow any of these adjustments.
On the other side you get more watch faces in Live Tile Clock 8.1 but I'm not willing to pay just for an additional watch face that will most likely make my startscreen more cluttered: the free watch faces are very basic and the paid ones are meh. Of course, if you need medium tile format, then Live Tile Clock 8.1 is your go-to app! I also uninstalled Live tile clock 8.1 because the live tile got stuck and stopped updating which defeats the purpose of a live tile while I never had any issues with TimeMe Tile.
It's good that we have at least a few options to choose from so that anyone can find the app that suits their needs
