Well first and foremost, I'd say write the way you feel comfortable or is most sustainable for your own enjoyment. It may be cliché, but the BTB should be for you first, not for the potential reader. This needs to be something you personally enjoy writing or it won't last long anyway.
Now as for my own personal preference, I can go either way but I'd say I like a summary for any weekly shows when it comes to matches. Maybe if its a "bigger" match happening on a weekly show, it can get more detailed. Then perhaps more detailed matches on the big shows/PPVs. I also tend to like a promo that is either written out or somewhat written out with some dialogue as I find that characters can shine more when there's dialogue versus just a summary of the promo. But if it's just like a quick backstage segment or something, a summary can be effective.
That said, one of my favorite BTBs of all time by the legendary Keefmoon was very summarized in its format. I think in the end it comes down to how well the booking is done, what story is being told, and how well is it told. Summaries can be just as effective and are more than accepted around here.
And hey this is my 1000th post on WS.
