Compression vs threaded valve for icemaker

[Rocknroj]

good day

i want to replace my icemaker supply line and valve.. there is a saddle valve in a crawl.. about 50 feet from the trap door and concerns me that leaks will go unnoticed.. soo...

my plan is to run 1/2" copper off a ' t' from where the saddle valve is.. in the wall i am planning on a 1/2" compression valve to 1/4" and a leftover plastic box from a wash machine.... then i can replace the valve readily.

Seems i can more readily get a leak free connection using compression fittings vs threaded.

Is there any good reason why not to use a compression type shutoff valve in this application?

From what i can find out most boxes have a threaded valve.. and lots of posts about leaks as well..

as an aside..,. why oatey, eastman and others don't post installation instructions... i cannot tell how to install these things without going to the store and handling it..???? or picture here..

thanks in advance for your thoughtful replies

Not a bad plan.
Compression angle stops and threaded angle stops have about the same chance to leak, depending on the installation.
