I think you’ve been fortunate that your ability to get one coincided with the launch of this revision, the value for money of the OLED deck when compared with the launch models is incredible.
Ultimately it will decide on how much you value the screen for causal play as I don’t think the other benefits (while good) will impact your experience as much as the screen.
That being said I decided to upgrade my deck from the launch model to OLED based on the amount of improvements and my experience moving to OLED on Switch.
Got mine last Thursday, ordered around 18:10-18:20 on release day, had no notifications through GLS the European courier but got an email from Parcelforce (UK) on the day of delivery with an estimated time slot.
I could check the GLS status through the Steam order page and tracking link provided there.
