Clear Case or bumper + Tempered Glass -> max drop protection

Hi, i'm looking for a clear cover, or a bumper with max drop protection
If necessary i'll add a tempered glass.

Some option, but no one agree all my requirement:

1)Rhino Shield bundle .. as seen on youtube the best in drop test... but 47€ , 58$ + IMPORT FEE
is too much and no pubblic review..
only 2 video on youtube and not good comment on amazon..
I need a real opinion !

2)X-doria defense gear , good in drop test , near to impossible to get in Italy ( no worldwide shipping ) :crying: deprecated :p

So i found some alternatives option(reading the forum):

1)SPIGEN SGP SGP11317 Ultra Hybrid Galaxy S6 Crystal Clear -> 13€ but no one speak about this ... so i think is not the best in drop ...
2)SPIGEN Neo Hybrid CC -> lot of people says it's good, ok but i never seen a drop test -> 27€

I'm open to evalute other option!

AND FOR THE Tempered glass
I'm getting confused:

Some people says that it's ok for drop , and many others says " it's only an anti-scratch protection "

But , if it's necessary for best protection in drop, (and seeing rhinoShield I think a quality one will help )
i'm oriented on CaseBase® Premium -> 13€ or more famous NILLKIN CP+ for 15++€

Conclusion..
I'm forgetting something ?
Other clear cover it will be good ?

thinking about price...
quality cover + quality tempered = rhino bundle
i'm really confused =)
