Generally good, in a generic sense. Some good insights. Some good charts, diagrams, etc. Dispensational leaning and doesn't really take a stand in regard to Arminianism/Calvinism. Once in a while I'm surprised to find some covenantal perspectives as well. It's what I've used for years, probably because I simply got comfortable with it and have written my own notes in it. The notes aren't as exhaustive as the MacArthur Study Bible. In quantity, they're probably more along the lines of the New Geneva Study Bible. Like most study Bibles it doesn't cover every verse, and especially the ones you really could use some insightful help with.
If you need a Bible to carry, then enjoy it. If you have one you like to carry, this one might be good for reference if you like to keep one around. I have several that I consult on occasion.
