Depends on you and what you enjoy. In my case I prefer having the new and exciting toy with the best features even at a higher cost. I would choose an OLED steam deck not just for the OLED alone, but also the substantially greater battery life and 90hz and slightly larger display. All of those together are a pretty big upgrade that warrant the extra cost assuming you will be using this device often.
