ML Dynamo 1000 vs REL 212 SE

I currently have dual ML Dynamo 1000 subs and am looking at switching out to dual REL 212 SE subs. These will be used for home theater and some 2 channel listening. How much better are they? Would they do well with SF Aida? (The No. 25 is just too big and I’m not trying to spend that much on subs along with an AIDA purchase). 

Current setup:
Pioneer Elite SCLX701
Mcintosh c2500
McIntosh mc1.2KW
Realistic Optimus Mach 3 (Will be adding SF Aida soon) 
Sonus Faber Vox
B&W CWM7.3
B&W CCM683
B&W 685S2
