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 Standard definition will be downscaled, because that is the practical ceiling for 3GP where MTS reaches Full HD (1080p).
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 video, stored in the AVCHD container since 2006, into 3GP, which uses 3GPP and dates from 2001. The codecs each container accepts decide whether the picture has to be re-encoded.
MTS comes from Sony / Panasonic and dates to 2006. It usually holds H.264 video with AC-3 or LPCM sound, and those streams set the ceiling for anything converted out of it.
3GP comes from 3GPP and dates to 2001. It holds H.263, MPEG-4 Part 2, or H.264 video alongside AMR-NB, AMR-WB, or AAC-LC audio, and without installing anything it plays on Android.
