Which operating system reinstall?

[Macintosh1984]

A friend of mine owns a MacBook Pro 13 i5 2.3GHz (Early 2011), 4 GB RAM. Because he wants formatted, for best performance, recommended to install El Capitan, or what previous version?

I'm in doubt between Yosemite and El Capitan, who is better?

I'd say El Cap at this point. I think it's just a bit more stable

El Cap runs as good as or better than Yosemite...

Thanks! Go with El Capitan!

El Capitan for sure, but I would also mention upgrading to a SSD if they already haven't.

Upgrading RAM do not help on performance?

For SSD, my friend need to replace super drive? Do you recommend a particular SSD kit?

RAM will help. SSD will be MUCH more noticeable.

Don't need to pull the SuperDrive, just replace the HDD with a SSD. Samsung and Crucial both make great drives.
