I hate to sound like a smartass but it really depends on your purpose.

For FFmpeg development, you need support for Bit-manip (B) and Vector (V). 
There are currently two eligible chipsets:
- Canaan K230: single (vector-capable) core, 128-bit vectors,
- SpacemiT K1 (or M1): octa-core, 256-bit vectors.

The later is available in several form factors: BananaPi-F3, Milk-V Jupiter, 
DC-ROMA laptop II, etc. Beware that cheaper variants come with only 4 GiB RAM, 
which is little for 8 cores.

N.B.: The market situation is fluid, so Osborne effect rules.
