I have no idea about the specific garlic supplements you mentioned. I have not seen any garlic supplements that come close to fresh raw garlic in term of being antimicrobial and antiparasitic. They are much better than nothing though. Some are quite expensive. Imo the deodorized ones may be on average even less effective than the non deoderized ones. There are still health benefits to deoderized garlic even if they aren't as good at killing parasites or bacteria and fungi. they are still a good source of sulphur. I also like the idea of using msm supplents, but some here feel it may redistribute mercury. Imo msm is a great source of sulphur that is also antiparasitic.
