That seems like a fair assessment to me. I've seen arguments for using Kendall's Tau over Spearman when comparing treatments, see this discussion and other linked questions on Crossvalidated, Kendall Tau or Spearman's rho?. But for just estimating the correlation between the two measures any one of them may be sufficient.

With only three measures for each a plot (and/or a table) is fine as well in my opinion. Especially with only 10 observations.
