Once was not enough -- TMZ decided to let another rookie photographer go toe-to-toe with one of our pros ... to see who takes the best shot with Patti Stanger from "Milliionaire Matchmaker."


The challenger -- Keith -- and our guy both hooked up with Patti in L.A. this week ... and now it's up to you to decide who did a better job.

So we gotta ask...

TMZ's "Take You Best Shot" challenge proved one thing -- it's not easy to ask a celebrity questions off the top of your head while simultaneously walking backwards through a crowd, shooting video.



TMZ took our finalist -- Nicki -- out in Santa Monica ... where she found Kyle Richards from "Real Housewives of Beverly Hills."

After Nicki took her best shot ... one of our photogs had a run at Kyle -- and now it's up to you to decide who's got skills.
