There is a set I installed on mine (every time I wiped them) that I use all the time. But it really depends on what you want to do with it. I have a 1GB swap file on the SD card, and I have the OS copied and booting from the SD card as well. I connect via samba and ftp and mess with php, python and the oled and gps extensions.
Seems like we are having about the same config. Need to look into it more. What started the whole thing was that the official FW for Omega2(+) does not have it compile for including POSIX Messaging (mqueue) which I need for communication between my threads. But with LEDE I can get that, but so far no correct Wifi. Anyways, for now, I gave up on the mqueue and rewrote my apps to use mutex's and cond vars for synch and communication between threads (Client Server for Consumer/Producer notifications). So I am back using the official FW for it and stress testing it with 50 clients throwing messages at it randomly between 0-100ms inbetween for each client does not stress it much, so I am still happy with the implementation.
Thanks for all the help so far though from both of you! I may come back later and see if we can revisit this.
