OK I am leaning towards copper pipe from floor to sinks

[Curiousv]

Please look at the picture...blue pex line is just temporary.
Currently I have galvanized pipes under concrete slab and female galvanized nipples are placed on the pipes that is coming from the floor. So there are 4 pipes coming from the floor ...two for kitchen and two for bathroom sink.
Now I am leaning towards copper pipes ...but obviously confusion is ...what is the best way to make a transition from floor galvanized nipples to new copper pipes..obviously I dont want to make direct connection using male copper adapter fitting.
So give me best idea which requires minimum no. of joints...I hate joints...so less is better.
I understand once I make transition from galvanized to copper ...I have to put an copper 90 elbow.
But after that can I put compression shut off valve directly on it or I should use brass nipple before I put valve?

Most people have no objection to using brass compression fittings with soft copper or brass supply tubes, and screwing those to galvanized. If they would remain accessible, good 1/4 turn ball valves would be a great transition. I am not a plumber.

This is the 1/2" FIP x 3/8" OD Comp Straight Stop Valve, Lead Free (Chrome)
SKU: 511-53-31

3/8 OD should work for a kitchen too.

What's wrong with sticking with the pex you've already run? You want less connections, that's the ticket.

He worries about rodents chewing the pipe. Said that and more in https://terrylove.com/forums/index.php?threads/there-is-not-enough-clearance-for-galvanized-pipe-what-is-the-solution.85410/#post-614096

I was suggesting to screw the valves to the galvanized pipe with no nipple. Then use copper or brass tubing up to your faucet. My way is not always the best way.

How did you plan to get from your valves to your faucet?

Faucet itself has long hoses which 3/8 female ends which I was going to connect to valves.
And from valves to galvanized nipple in floor (as shown in pic) was my question ...
I thought you suggested brass nipple for that ....

Well here is my thought process now...buy brass nipple with both the male ends ...one end will go to floor and other end will screw to valve and from valve directly to faucet ...
