The only reason I "upgraded" was, at first, to try it since what I know about Apple which is they are not "going back." This is not Lion which you could ignore until they came up with a better OS. So the new architecture is the new architecture, and programs will eventually adapt to it.
For you, who has an SSD, you should have no problem though exercise the usual "clone first/back-up/sacrifice a virgin" precautions.
The question is "do you need" it. I would state that you do not need it now, since I do not need it, and if there is anything certain in the world over-rated Paul McCartney songs which we live in: it is all about me. I am unaware of any mainstream programs only compatible with High Sierra other than some updates: for example, the much lov'd Onyx has a version for High Sierra and you can still use their Sierra.
Problems:
The major "irritating" problem is that your Mac stops automatically recognizing Ex-HDs. Mine are encrypted so perhaps that is an issue. Mine are also LARGE and partitioned with one handling back-ups to my Int-HD and the other partition handling "stuff"--raw data like pictures, documents, highly artistic French harem anime . . . for research, of course, for a friend.
I usually notice that if I hook up the Ex-HD either nothing happens or it only recognizes and asks for the password for one partition. I have to use Disk Utility to mount the partition or the whole Ex-HD. Granted, my Ex-HDs are not SSD, so that may be a problem.
Other than that, Mrs. Lincoln, everything else seems to run fine as far as I can tell. So you probably are better off, if you do not need it, everything is fine, just waiting until Apple [PBUT--Ed.] sorts it all out.
