8* Mine vs 10* Music Store?

I am currently helping out someone by filling in a spot in their Mining Corporation, and the alcohol cooldown reduction perks is really helpful since I have been focusing on nerve a lot recently. There is also free rotational trains which I get roughly about once every 2 days and 250k salary (I was just helping them out and my WS aren't high)

However, I also got an offer from a 10* Music Store which has perks such as passive bonus to BS and gym experience which seems to be really helpful too. However there is no salary since the perks pay for themselves essentially and usually trains are for newbies, not players who are already kinda established.

Which do you guys think is better?

Music Store, by a county mile. Spend e on training and open better gyms quicker.

In my opinion.

The choice is money vs perks and the money seems low but that is a guess since we don't know your actual work stats and EE merits.  Trains are not necessary but everyone can benefit from them.  Sounds like the music store is a better fit if you are actively working on your BS.  

If you want to grow your BS then Music Store. You unlock gyms much quicker meaning you'll get bigger bang for every E you spend in the gym much faster and get to unlocking the specialist gyms which accelerate the gains further faster.

If you don't care about BS, don't do the Music Store!
