My 2 cents:
1) Delta sigma : Cannot be used. Because of 4 Inputs , we loose noise shaping [every time we reset, memory is lost] . 2)Pipeline ADC : Do you care about latency? If yes Pipeline is overkill. use Cyclic or SAR instead. 3)Flash : Cannot be done. Need Fancy/expensive folding techniques. 4)Slope techniques: May be slow, requires huge oversampling. Good for multiplexing, as you can have separate registers and filters in digital domain. Again speed is issue.
Historically SAR has been published with higher ENOB. I am inclined towards SAR.
