Qwen 3.8 Flash-Next on 64GB RAM + 16GB VRAM, worth it over a fully-loaded 3.6 35B-A3B?

5080 16GB, 64GB RAM. Currently on 3.6 35B-A3B (Unsloth quant, fits fully in VRAM) and happy with it. Anyone tried Flash-Next at Q2/Q3 on a similar setup? Worth the switch, or should I stay put? Asking before committing to a 30GB+ download.
