They both look like good servicable bicycles, aluminium frames is the the way to go, light and strong, stainless spokes are good, strong and dont rust, looks like eight speed Shimano cassette and parts (24 speed)
Bicycles are a lot of fun
They are so much fun that after many years in the rat race I pursued my hobby of mountain bikes and importing them directly from the factories in Taiwan and distributing over the region, I ended up with five retail shops in Singapore, picture of just three of them, Holland Road, Selegie Road and Tanglin.
