Years ago I collected Frontline ACW, Crimean War, Napoleonics and Colonial Classics. Their figures were very competitively priced, robust and well painted. However, as other makers such as K&C, WB, TCS, JJD and FL evolved I felt they were superior in sculpting, poses and painting. Frontline figures are a good value but I find them chunkier and stiffer in their poses than the other makers. Recently I bought some of their SYW Prussians thinking they might go well with the new JJD Prussians. They are much larger and chunkier so I probably will not add any additional figures from them.
It comes down to a matter of taste.....we have many different opinions and collector preferences on this forum. I will say again that they are priced very well and the figures stand up to handling and the occasional "fall" very well.
