what is the difference between reference genome sequence from UCSC and ensembl ?

Question

[Pei]

Hi:

To map reads, (small RNA sequencing) to reference genome, I'd like to download fasta-format sequence first.

As both ensembl and UCSC provide these resource, I wonder if there is any difference between these two resources?

For my purpose (mapping of small RNA sequencing reads), which would be a better choice?

Thanks!

Best
