About 3GP
3GP is a container format defined by the 3GPP for mobile phones. It is a simplified relative of MP4 that typically holds H.263 or H.264 video with AMR or AAC audio.
Videos recorded on older mobile phones, especially before smartphones.
3GP videos are usually low resolution and heavily compressed, and converting them cannot add detail.

Why is the video from my old phone so tiny and pixelated? 3GP was built for small low-resolution phone screens on slow mobile networks, so there is no detail in the file to recover — the source simply never had it.
About MP4
MP4 (MPEG-4 Part 14) is a container format standardised by ISO. It usually holds H.264 or H.265 video with AAC audio, and it can also carry subtitles and chapter markers.
It is the most widely supported video format: phones, browsers, smart TVs and video sites all play it.
The video inside an MP4 is almost always compressed with a lossy codec, so every re-encode loses a little quality.
Why convert video to MP4? Almost every device, browser and platform plays it, so an MP4 almost never needs a second conversion.
