JP1 Remotes

Since I am downsizing and thinning my herd of remotes. I am curious to see if anyone has found certain remotes that are better at Learning a signal than others ?
I want to keep a few just for learning a signal even though using IrScrutinizer is the better way to go.
I am thinking that some of the older JP1 remotes might be better at it since they also use a larger LED for sending and receiving a signal
Any thought on this ?

I find using a Xsight Color super handy for learning.

I think they're all pretty much equal in that regards.
