The best thing about logicspot is that they are experts for magentospecific projects so you can be sure of top notch support if any issues arise or when it comes time to update your site with new features/functionality as per industry standards etc..
Nothing really but I suppose this could change over longer periods especially since there have been no major improvements made recently by their team members (at least not visible). They also tend do come across quite pushy at times which tends make me feel uncomfortable after some interactions where we get into long "discussions". Their pricing structure does seem fairly high compared to other companies out here although perhaps fair given what's provided! As mentioned above - great choice overall unless something else pops up cheaper than them within 2 years maybe?
