London IBD - Industry Group VS Product Group

Hi all
I know this is a recurrent discussion but I would like some help and fresh insight on this.
Next summer I will be working in IBD in London and in the next weeks I will have to choose my preferences for which teams I want to work for.
I know that if you work in an Industry Group you work with all types of deals and if you work in a Product Group you work will all types of industries, but this is not enough information for me to decide..
Basically in my bank the product groups are: ECM, DCM, Lev Fin, M&A (my top choices for the products are Lev Fin and M&A).
I do not have a specific industry that I love, but people have been telling me that in the product teams the hours are worse and that the job is more repetitive..

So basically, would you recommend to go to a industry team or product team?
Thanks for the help
