Im one of those so-called 'oral success stories'. I can speak well enough that the average hearing person doesn't pick up that I'm deaf. Kids usually say something along the lines of 'you speak funny'. Everyday, to speak orally takes concentrated effort and is exhausting. To understand what others say is even more so, since i only hear vowels (no consonants) its like playing 'Wheel of Fortune' every waking hour. It very much depends on the setting and surroundings. Visibility, lighting, seating, view of mouth and face. As you all well know. People don't understand why I prefer and advocate for sign language.
I'm the same way i suppose i speak really well but I guess i have that "deaf accent". It is exhausting though i love going home and taking off my hearing aids and just unwinding. It helps i wasn't born profoundly Deaf only with mild-moderare hearing loss that progressed over time due to an autoimmume condition. I was in a bad car accident when I was 5 which caused sudden severe-profound hearing loss. I look at it now as just having sped up nature ;-) its funny i did much better in speech classes throughout elementary school than my little brother who only had moderate hearing loss. I've always had strong language skills, i taught myself to read in preschool, even after the accident i was very talkative. I picked up on SEE SE and simcom the systems I used in school quickly. I wish I'd been exposed to fluent ASL younger, its much harder being older and having bad habits to rewire in my brain.
