This was already answered on the forums if you'd look next time, It's around 160-210 Average would be 185

is he good?

You need certain ninjas like samui, omoi, and darui to work with him and if you aren't willing to switch to a certain class (lightning or earth), don't bother. If you want to know the usefulness between 3rd raikage, susanoo sauske (normal version and skillbroken version) and 4th raikage (normal version and skillbroken version), there has been discussion about him: https://forum-narutoen.oasgames.com/page/show-post-25044-1.html

He is good if you build a team around him. A guy already got him with 210 seals, check youtube. If you go for him you def will have omoi and samui too to build with him. if you get them here is a good lineup:

Samui | Lighting Main | Ay

X X X

Omoi Xclones Xclones

Summon: Monkey King

Talents: 23432

10 Combos, lots of control, tankiness, shields, alot of chakra recovery, buffs, clones. This team works best if you have high ini and power though.
