Looked like you were getting off to a good start. Hate to see you give up so quickly.
I'm not fond of adding/creating profiles from GEDCOM myself, I'd rather do it manually, but, on WikiTree, neither way of adding/creating profiles is going to be swift or automatic. I've been here two years (almost exactly) and I've only added between 900-1000 profiles. I know people who've added far more in the same time period but I like to write very complete narrative biographies and I spend a lot of time trying to find every source I possibly can (and I'm a perfectionist.) I have my full tree of over 21,000 individuals on Ancestry.com, but I know I'll never be able to add all of them over here in my lifetime, but I'll be doing the very best I can on the ones I do. I started with my immediate family and direct ancestors and now I'm filling in the branches. I'm much more proud of the 900+ well-sourced profiles I have created here than having 21,000 on Ancestry.com.
As Linda said, not everyone in your GEDCOM will need to be added to WikiTree. You probably discovered many matches when you were processing your GEDCompare report.
Anyway, I encourage you to look around WikiTree, think about what attracted you to it and what you want to accomplish in your genealogical work and how WikiTree might help you accomplish your goals. If, then, you still decide WikiTree is not for you, I wish you all the best.
