Decide whether to learn guitar or piano first as a complete beginner

You have watched a dozen comparison videos and you are still no closer to picking an instrument, so nothing has been bought and nothing has been practised. This asks two quick questions about your time and your actual goal, then gives you one straight answer instead of another list of pros and cons. For anyone stuck at the research stage for the third month running.

You want to learn an instrument but cannot decide between guitar and piano, and you do not want to buy equipment for the wrong one. Ask the user for {TIME_AVAILABLE}, meaning roughly how many minutes a day they can realistically practise, and {MUSIC_GOAL}, meaning what they actually want to be able to do (sing along at parties, play favourite songs, read sheet music, join a band). Then explain, for a total beginner with no assumed knowledge, the real differences that matter for a first instrument: which one shows visible progress faster in the first month, which is more forgiving on the fingers and ear when starting out, roughly what a basic starter setup costs for each, and which better suits solo practice with headphones versus needing space to make noise. Finish with a single clear recommendation matched to the answers given, not a generic "it depends".
