I prefer the 7 segment display over the OLED personally.  More reliable, liquid/shock resistant, very unlikely to have a segment go out, easy to see in daylight, and I like the looks of it better.  The OLED offers me nothing that I need & has several drawbacks compared to the 7 segment display for my use.  Just my opinion.
