Midwife vs Doctor?

I'm at a maternity clinic with 8 doctors who deliver at Royal Columbian hospital , New Westminster. I've seen them 1-2times b4 a miscarriage last summer and another 2 times now. Love the secretary, docs are knowledgeable but cold of the 2 I've met. Just got accepted into a midwifery that delivers at Ridge Meadows and met with 1 of 3/4 of them quickly... She seemed knowledgeable too and likely more support but I'm not sure which way to go? Midwife or Doc? What's your experience? 
Ps- if you switch & it doesn't work, can you switch back?
