Best reward tanks for the Referral Program

Hello,

My recruit and I are about 13 points away from completing the final referral program stage. Once we reach the end, what reward tank would be the best for us to pick?
The recruit has these options:

    VI      Dicker Max   

    VII     Panther/M10   

    VI      Tiger 131   

    VI      Sherman VC Firefly   

    VII     KV-122   

    VII     SU-122-44   

    VI      Pz.Kpfw. IV Schmalturm  

    VII     AT 15A   

    VII     T26E3 Eagle 7 

While I have these options:

    VIII        Panther mit 8,8 cm L/71 

    VIII        FV4202 

    VIII        AMX M4 mle. 49 

    VIII        8,8 cm Pak 43 Jagdtiger 

    VIII        T92 

    VIII        112 

    VIII        T26E5 

    VIII        AMX Canon d'assaut 105 

    VIII        Kanonenjagdpanzer 

(Alot of my matches tend to be in Medium, Heavy, and TD tanks. I will play LTs but not as often).

Thanks!
