Wow! I am surprised that there are so few with a "house" yeast! I DO HAVE ONE!
34/70 - I make nearly everything with it. Long ago I used Nottingham for many beers but once I found that 34/70 would do anything nottingham could I switched. My brown ales - 34/70. Porter/stout - 34/70... Honestly, everything except hefeweizen and belgians. But, I rarely make Belgians.
So, this is not to say I DON'T use other yeast - I do. MJ M20, MJ M15, Koln... I used to use WLP300 but now that I've found M20 I don't even bother with it anymore.
What I can say that I DO NOT use is: Liquid Yeast. With the exception of WLP300 I gave up on it back in 2018 when I started using Notty and 34/70 (stopped with WLP300 this year as I found M20 works awesome!
... Dry yeast reigns supreme in my opinion. Makes brewing so much easier and cheaper. I buy 34/70 by the brick and separate into vacuum sealed pouches. Remains viable so much longer than liquid yeast and saves a TON.
I imagine that I will continue to try new dry yeast strains as I find them but mostly I just stick with the HOUSE yeast 34/70.
Sorry to ramble
