I had a stain on my Sony A6000 sensor today that the orange gel stick could not remove
Used a sensor swab and got rid of it.
Form my experience cleaning just the a6000 sensor, the gel stick works well for removing dust where a rocket blower can't while the sensor swabs can clean stains where the gel stick can't.
If I had to use only 1 cleaner, I will probably go with the sensor swab as its more effective and cheaper ~ $15 for the swab kit with 12 pieces of swabs VS $ 50-80 for a gel stick which can be reused probably indefinitely.
I feel the gel stick is way overpriced. Probably a mark up for being "made in Germany" however the made in china VSGO sensor cleaning kit works just as well if not better
