What do you think? What are the pros and cons of device mapper v/s block device driver
Block device driver does exactly one thing - provides a driver for a a generic block device. If all you need is a generic block device, use this. Device-mapper provides targets that do things other than a generic block device. Stuff like crypto support, logical block forwarding and mapping to support things like LVM, multipath support, software raid, caching, etc. Basically, look around in drivers/md at the already existing targets.
