I know this is a broad and very subjective topic, but here goes:
I'm basically looking for an obscure pet project composer to get to know. I'd love opinions on any of the below composers, a list I've compiled based on some specific criteria. They're all (Russian/Soviet) 20th century composers (some have works from just before 1900?) who've put out some number of both symphonies and string quartets, and they're at least somewhat (if not very) obscure.
- Maximilian Steinberg
- Boris Asafyev
- Vladimir Shcherbachov (only a suite for SQ)
- Lev Knipper (also spy!)
- Alexander Tcherepnin
- Gavriil Popov ("symphony for SQ")
- Vissarion Shebalin
- Boris Arapov
- Dmitri Klebanov
- Nikolay Peyko
- Aleksandr Lokshin
- Andrei Eshpai
- Vladimir Dashkevich
- Youri Boutsko
- Boris Tischenko
- Alexey Rybnikov
- Alla Pavlova
I know that's a lot, but I'd be curious to get anyone's opinions/recommendations if any of these stand out, not a rundown of each of them. I've been listening to a number of Shebalin's works so far, and am at least interested to continue listening. Thanks!

Ovchinnikov, especially 1st symphony.
Yevlakhov
Slonimsky

Alexander Tcherepnin was a mentor of mine in the 1960's, and yes, his Piano Concertos are well worth your time, as are the Piano Sonatas, and the four symphonies.  The latter are not epics by any means, but are somewhat Liadovian in that they are short, charming, thoughtful, and just fun works.

Vyacheslav Ovchinnikov is not on your list: recordings are difficult to find, if not impossible, but YouTube has a good number, as does this streaming online service:

He is still alive, c. 80 years old, and is perhaps most famous for his film scores for War and Peace, Andrei Rublev, and others.  Ovchinnikov's First Symphony is most excellent.

The above was recently read by a member: Vyacheslav Ovchinnikov died 3 or 4 years ago.  We still await good, modern recordings of his works!
