I have traveled extensively in Indonesia, and have always preferred Go-Jek over Grab, and I have a feeling I share the same with the number of drivers and riders, at least in Medan, Jakarta, Bandung, Yogyakarta, and most of Java.

I also don't think being an Indonesian company has challenged Go-Jek in any way. Traveloka, Tiket.com, and Go-Jek are one of the most prominent businesses in Indonesia, and they all look like well-oiled machines.
