Appraisal request for pizzamerch.com / incswap.com / prodigitalwork / muiky.com

I'd love to hear your thoughts if you know domaining and you have a sec. Are these domains worth anything? Why/why not? I'm still not sure, beyond phonetics and constonant/vowel patterns, how people evaluate domains ?

pizzamerch : a good fit for someone having a pizza business (local or e-commerce)
incswap.com : a good fit for someone doing business trading, business brokerage etc
prodigitalwork.com : a gootfit for someone doing digital marketing or work
muiky.com : 5 letters domain name easy to remember

What "merch" would you sell?
2 and 4 fail that "radio test" for spelling and are confusing.
3 word domains are tough, but it's generic.
