High altitude in March?

Hello,

I am looking for recomendations for enjoyable 6,000m+ climbs that are possible to do in March and that require limited technical knowledge (basic mountaineering skills are fine). So far I came across the following options:

• Ojos del Salado: I watched some videos and it looks very desolate and ugly (rocks only, no views around) - how is reality? I don’t want to go crazy being stuck “on the moon” for 1+ weeks…
• Chimborazo: Also looks fairly "boring" but not sure if that is just a wrong impression from videos I saw? What levels of mountaineering skills are required?
• Cotopaxi: Looks most beautiful - what level of mountaineering skills are required (I saw some fixed ropes)?
• Island Peak & Lobuche East: Both offer best views around - any recommendation one over the other? I have read that IP has become more dangerous to climb due to lesser snow?

Any other peaks I am missing (I have checked guidedpeaks as well already), or otherwise any experiences with any of the above?
