Garmin or Apple watch

Hi guys! Please help me decide. I’ve been thinking of investing sa okay na watch. I want something na mamaximize ko talaga yung use niya. Also, can you recommend anong model ng watch yung best? Yung budget friendly sana.

For context:
- been running for almost 2 years (hindi naman as athlete but naging lifestyle ko na rin)
- runs 2-3x a week
- swims 1x a week
- starting to enjoy biking na rin
- hikes every 2-3 months

Sabi nila okay apple watch if naka iphone na ako kasi para maaccess ko rin yung messages, etc. Medyo hesitant ako sa battery lang. Thoughts?
