None, if you're looking for a device with the features, resilience and capacity of an ASR like that, you need to go and check other brands.
Closest you can get is a CCR 1072 and those are only comparable (and not 100%) to the ASR1001X
i agree but i think the ccr1036 o 1072 can compete only with lower end first (out of market now) asr 1001 and 1002 models not the previous X models which can escalate to Higher levels of performance and scalability or latest X models who escalate even more
having said that we can identify up to what level of performance mikrotik can replace cisco, beyond this point you have to go beyond routerboards and assemble a powerfull x86 box with all what that implies
or go cisco or juniper or any other
keep in mind maybe you need asr9xxx for your master core router but you can populate your access and distribution layers with several ccr1036 and ccr1072
