It's the violin, piano is rarely used in orchestra pieces.
Orchestras are usually tuned to an oboe. The open note, (that is, the note an oboe plays without any fingering), is an A, and the orchestra tunes best to that note. When a piano is featured as solo instrument, the orchestra tunes to the A of the piano, because it's easier for them to adjust their pitch than for the piano.
Most American orchestras' will feature or highlight violin music every season, or have a "string instrument highlight". The five orchestras that are considered the best in the United States are the Cleveland Orchestra, the Chicago Symphony Orchestra, the Boston Symphony Orchestra, the Philadelphia Orchestra, and the New York Philharmonic.
I took piano lessons in first grade and picked up the violin in fourth grade. Personally, I liked the violin better but it's probably best to let the child decide which instrument they prefer. Though, to be fair, they'd have to learn two clefs (bass and treble) to play the piano and only one (treble) to play the violin.

I'd say the violin. You hear sayings such as: "World's smallest violin." The violin has that tug on the emotions... It's unstable too.. teetering on each note... But you can stabilize the emotion by holding it longer.. I play piano, but I really like the violin for it being able to stand alone (along with other violins) lol.
The piano is an amazing instrument, but it’s very different from the violin. It is more rewarding at first, since you don’t have to worry about intonation, just about coordination. Things start to get difficult later on, when you start to play pieces with lots of voices and you must decide at every moment which one has to be the main one, which one the second, third, etc. Also, music sheets are more difficult to read than violín ones. There are lots of incredible piano/keyboard pieces, and putting in the effort to reach even the technically easier ones is well worth it. If you want to play the violin, the very best preparation to that is just to start playing the violin. Don’t take any detours, because it is difficult enough as it is. It’s definitely not true that playing the piano or the recorder is a better preparation to playing the violin than playing the violin

Bach is best know for playing the piano, or piano forte.
The violin is a harder instrument to master than the flute. Both can be beautiful. It is also good to learn a lesser used instrument such as a bassoon or viola.
