Choosing DJ equipment often comes down to a practical question: do you want the lower listed price and a straightforward USB-connected controller, or are portability and PC/Mac compatibility more important? The Numark Party Mix and AlphaTheta DDJ-FLX2 are both black tabletop controllers centered on mixing two decks, with built-in mixers and loop/sampler controls. Their listed prices are separated by $60, while their condition and connectivity details point toward different priorities.
Quick verdict
Pick the Numark Party Mix when the lower listed price is the main driver and a USB-connected setup suits the way you plan to play. Pick the AlphaTheta DDJ-FLX2 when you specifically want a portable controller that is listed as compatible with PC and Mac. Both controllers have 8 pads, so pad-based performance control is not the deciding feature here.

AlphaTheta DDJ-FLX2: The AlphaTheta is the stronger match when portability and stated PC/Mac compatibility are central to the setup. Those details make the DDJ-FLX2 distinct from the Numark in this head-to-head, while retaining the shared tabletop format and built-in mixing controls.
Product notes
Numark Party Mix Double Deck DJ Controller, Built-In Mixer, Loop/Sampler, USB

The Numark Party Mix is a sensible direction for DJs seeking a black tabletop controller with two channels and an 8-pad layout. The combination of a built-in mixer with loop/sampler controls gives the Party Mix a focused set of creative controls for working across its double-deck arrangement. USB connectivity is also specifically included, which is useful for shoppers prioritizing that connection type. The main tradeoff is condition: this Numark Party Mix is listed as Used, rather than open box. Choose the Party Mix when its two-channel format and lower listed price matter more than the AlphaTheta's portability and PC/Mac-compatible feature callout.
AlphaTheta DDJ-FLX2 Black 2-Deck DJ Controller Built-In Mixer Loop/Sampler

The AlphaTheta DDJ-FLX2 is aimed at a shopper who wants a black, portable tabletop controller with a stated two-deck configuration. Its built-in mixer and loop/sampler controls maintain the same central performance approach as the Numark, while the DDJ-FLX2 adds the listed PC/Mac-compatible detail. That makes it the more targeted choice for a computer-based DJ setup where platform compatibility is a key factor. Its limitation in this comparison is the condition distinction: the DDJ-FLX2 is listed as Open box, which differs from the Numark's used condition. The DDJ-FLX2 also carries the higher listed price of the pair.
Final choice by use case
Choose the Numark Party Mix for a two-channel controller at USD 100.00, especially when USB connectivity is the feature you want emphasized. Choose the AlphaTheta DDJ-FLX2 at USD 160.00 when portable operation and PC/Mac compatibility are more important to your DJ setup. Both keep the decision centered on two-deck mixing, built-in mixer controls, and loop/sampler functionality.
