It will depend on your requirements. 9001 is small, deep, but powerful,
capable of pushing 120Gbps. ISR 4461 and ASR 1001X/1001HX
can’t match that (1001HX is 60Gbps) and for example can do
VPN crypto which 9001/9901 can’t (if you’re willing at some point in
future to terminate S2S/RA VPNs).

As I already responded to James, 9001 is not going EOL anytime
soon - at least not until June 2020. 32 bit is still an valid option and
will be for years to come - we have hundreds of thousands of systems
deployed with it.

*If* however you want to go for full-scale/future-proof design, either
go with ASR 1k or ASR 9901 (both of which run 64b code, IOS-XE and
IOS XR now).

And refurbished is only good if you don’t need official service & support.
