Hardware tier
Jellyfish RGBIC-RD: aluminum track, ~4-inch pixel pitch, IP67, -40°F to 140°F operating, lifetime track warranty.
Govee Pro: plastic clip-on housing, ~6-inch pixel pitch, IP65, 14°F to 122°F operating, 1-year warranty.
Both produce 16M colors. Govee shows visible cable along the run; Jellyfish hides everything in the channel.
App and control
Both have decent apps. Jellyfish ties into Control4 and Nice Elan; Govee doesn't. Both work with Alexa and Google Home.
Jellyfish app pattern library is larger and the patterns are more polished. Govee has a more active social/sharing layer if you like that kind of thing.
5-year cost reality
Govee Pro DIY: $500-$700 hardware + your time + 1-2 replacements over 5 years = roughly $1,200-$1,800 all-in. Jellyfish Standard installed: $2,800 once.
Govee wins year 1. Jellyfish wins year 4+. Depends on your timeline and how much you value 'set it and forget it.'
