Currently these "gospel" labeled products have not actually addressed any needs nor innovations of the genre. In fact the genre itself borrows from others genres so much that it's sonic and physical needs are for the most part undefined. Most urban "gospel" churches are storefront in nature with little to no budgets and non-tech oriented mostly self-taught players whom lack understanding or the cares of what is the "right equipment".
Culturally (here comes a stereo-typical broad statement...) we like a fat bottom lows that punch and a mid-range that is muddied by licks from 3 right handed keyboardists and an organ. This is not enough to define the needs of the musical landscape.
Drummers whom cannot tune a kit and break cymbals like breathing cannot define the equipment needs of the musical landscape accurately. Once properly educated in gear and application then presented with example a true addressing of the needs may prove fruitful.
Example of the confusion that exists now:
A church with little to now acoustic tile, carpet nor padded seating then drapery and floor to ceiling glass windows on three sides (because it use to be a clothing store) is a terrible place to generalize drum needs. The keys , bass and organ are amped. The drums are fronted by plexiglass and placed in a corner or against a back wall.
This type of situation does not give you a way of isolating sound so all the tuning will be off unless electronic tuners are used every song. the air conditioner will alter the instrument response cause the instruments to loose tuning easily and the volume is double because of all the reflecting hard surfaces. A company cannot accurately address these needs without experiencing them. And the customer cannot ask for a need that they don't know that they have.
Solution (drums): small jazz kit, 10x6.5", 12x7" 14"x6.5" snare, 14x14" floor on legs, 20" kick. Mic the kick (D6, D112, PG, etc)and two overheads... acoustic tile on the wall behind the drums, headphone monitor and remove the plexi-glass or use a short 4ft piece however a 3ft padded wood barrier would be better. Thin, dry cymbals (tight lathing and or hand hammering with small bells). Nylon Rutes, brushes, broom stick, maple drum sticks with elongated tip. Wood hoops on the snare.
[all these things promote full sound with low volume thereby not hindering the player nor the atmospheric needs: quick, full speak - short sustain]
This comes from serious gear study, experience with gear application, and wisdom. This is not the investment of these companies. And the solution I described is not a "gospel" setup it is a professional acoustic jazz setup used for a convention of wedding band in most usage. So if we look at the product offering we see that there is nothing new for the "gospel" drummer.
