I've been a big Borderlands fan for 10+ years. I played through the first one multiple times and loved it. My wife and I bonded over BL1 when we first started dating.
Was super excited for BL2, and have played it many times throughout the years.
But the pre-sequel was a let down, and BL3 felt soulless and lacked the same spark as BL2.
Tiny Tina Wonderlands was great, and felt like a return to what made BL2 so fun.
All that to say, I don't have high hopes for BL4, nor will I be paying $80 for it. It just feels like they're coasting off the brand name at this point and trying to exploit longtime BL players like myself.
I never played the Tales from Borderlands myself, but my wife did and she really enjoyed it. She said it added a lot to the story lore presented in BL2.
I did enjoy the Walking Dead telltale game along with the Wolf Among Us, though.
