Because 3GP supports H.264 just like MTS does, the video stream can be carried across without a quality-costing re-encode.
Only one audio track will be kept. MTS can hold several, for example alternate languages, but 3GP supports a single track.
Anything above sd will be downscaled, because that is the practical ceiling for 3GP where MTS reaches hd.
3GP is built for streaming and progressive download, so the result starts playing before it has fully loaded, which the source format does not do well.
At 1080p, MTS typically runs around 23 Mbps while 3GP sits near 1.1 Mbps, which is the main driver of the size difference you will see.
This page converts MTS files, stored in the AVCHD container since 2006, into 3GP, which uses 3GPP and dates from 2001. The differences between the two containers decide what changes in the result.
MTS comes from Sony / Panasonic and dates to 2006. It carries H.264, which is what determines the quality ceiling of anything you convert out of it.
3GP was introduced by 3GPP in 2001. It carries H.263, MPEG-4 Part 2, H.264 and has native playback on 1 of six platform categories, which is the practical reason to choose it as a target.
