I've used both 11013/14 a few times between SBC and LTT/TNA/PUNE, and here's what I've noticed.

This train, after getting upgraded to LHB coaches, has become like an AC Express! The 2 GN compartments are always crowded. In the old ICF days, it only had 6 AC coaches. The LHB coaches used now are a bit old, but I have no complaints otherwise.

If you book from SBC to PUNE/TNA/LTT, you might end up on the waitlist, so try booking from SA or Hosur to your destination. It's worth paying a little extra. This train is quite popular.

The pantry only serves vegetarian food, but it actually tastes good. Much better than the unhygienic and disgusting food on the Udyan Express, which gave me a stomachache.

The coaches are mostly kept clean, even the Sleeper Class in my experience. The staff comes on board at stations like Solapur and Pune to clean.

Negative 1: Sometimes, both the UP and DN trains can be really late at SBC, but they make up for it later in some cases.

Negative 2: There have been instances where the train got diverted, causing Bangalore to lose its direct connection to Mumbai through this train. Even as I'm writing this tip, it's temporarily diverted (maybe to prioritize the CBE-BNC VB or to avoid congestion on the SSPN single line?).
