oloneo photo engine - easy to use. preset can be used for batches. antighost only works good if images are not misaligned. denoising option genious (stacking multiple images per position with identical focal/wb/aperture/shutterspeed - but images dimensions must be equal in w/h); also interesting relightning feature.
photomatix pro - many options - fusing and/or tonemapping. antighost good in auto mode, best with manually. batching not so fast like enfusegui.
EnfuseGUI (free/donationware) - for mac and PC - batch processing easy - some try and error needed until best fitting options are found - but than very fast processing huge amount of images. Antighost missing, images should be alligned perfectly.
