should I take ryujin jakka?

[email protected]

hello!

so I have katen as my zan for a good year now, and her attribute bonus levels are very well updated, my team is now sexy kukaku, main + yhwach, kirinji + shinso gin
but i will soon update my team when i get muken and my team will be like this

                 muken
kirinji          main
shinso gin   yhwach


i heard that there is a high chance that ryujin jakka appear in ubp soon and since he share the same attributes as katen but with higher numbers, i'm wondering if it's really worth it to spend my vit? does he fit better than katen with muken and yhwach?
