Sure, but that could be said about thousands of companies in every industry. I can't imagine it having any effect at all on your individual ride experience in Orlando or anywhere else.
In the Orlando market, I think both companies are strong, and will provide good, reliable service at a fraction of the cost of taxis. And in a few weeks, they will both be able to pick up with all classes of service at local airports.
A customer's experience on a particular ride depends almost entirely on the driver behind the wheel, and as you noted many drivers drive for both companies. Any driver should be able to respond in a reasonable time, pick you up safely, be courteous and respectful, and drive you from A to B safely and without drama.
Like anything else, there will always be that one odd situation that is less than magical.
I drive for both companies; I have 800 or so drives for Uber and a little less than 200 for Lyft. Out of almost 1,000 rides, I have had exactly two problematic riders -- one Uber and one Lyft -- but nobody so bad I had to end the ride and kick them out. (Full disclosure: I drive part-time, 80% weekday mornings, occasional weekend dinner hours, and zero drunk hours, so my clientele is much better than average.)
The tipping thing is awkward, but honestly I think it's greatly over-exaggerated. Fares, not tips, are the keys to driver incomes.
Orlando has possibly the lowest rates in the U.S. for both companies. I think only Detroit is as low. An UberX or regular Lyft ride in the Orlando market pays the driver $0.4875 per mile. That's why the turnover rate is so high -- a recent study said that only about 4% of drivers drive for six months.
