More advanced mixed model questions belong on r-sig-mixed-models <at> r-project.org , but the answer to this one is: either should be fine, unless you want one of the features that only lme has (reported denominator df/p values, R-side effects such as correlation and heteroscedasticity models) or one of the features that only lmer has (efficient fitting of crossed random effects, GLMMs).
